You do not need to know which way BTC will move to profit from a major economic event. You just need to know that it will move. The long straddle is how you trade that conviction.
A long straddle buys a call and a put at the same strike and expiry. It profits from a large BTC move in either direction
The ideal setup is around major macro events like CPI prints, Fed decisions, and ETF rulings when large moves are expected
The breakeven is the total premium paid for both legs. BTC must move more than that amount for the trade to be profitable
Entry timing matters. Buy before IV spikes, not after. Buying into elevated IV means paying more than the expected move justifies
Maximum loss is the total premium paid for both legs. A long straddle has no margin call risk beyond that initial cost
As a non-directional options strategy, the straddle removes the need to predict which way BTC will move
What is a long straddle and why does it exist?
Most options strategies require a directional view. You buy a call because you think BTC will rise. You buy a put because you think BTC will fall. But some of the most predictable moments in crypto markets are not about direction. They are about magnitude.
A long straddle is the strategy built for exactly this situation. It involves buying both a call option and a put option on the same asset, at the same strike price, with the same options expiry. You are not betting on direction. You are betting that BTC will move significantly in one direction or the other before the options expire. This makes it a core non-directional options strategy.
If BTC rallies strongly, the call gains value. The put expires worthless but the call more than covers the combined cost. If BTC crashes hard, the put gains value. The call expires worthless but the put more than covers the combined cost. The only scenario where the straddle loses money is if BTC barely moves at all and both options expire with little to no value.
This makes the long straddle one of the most intuitive strategies for traders who follow macro markets but do not have a strong directional conviction. That describes most traders in the hours before a major economic announcement.
What is the difference between a long straddle and a strangle?
The long straddle vs strangle distinction is one of the most searched questions in options education, and the answer is straightforward.
A long straddle uses the same strike price for both legs: you buy an ATM call and an ATM put at identical strikes. A strangle uses two different strikes: you buy an OTM call above the current price and an OTM put below it. Both strategies profit from a large move in either direction.
Feature
Long straddle
Long strangle
Strike placement
Both legs ATM, same strike
OTM call above, OTM put below
Upfront cost
Higher - ATM options carry more extrinsic value
Lower - both legs are out of the money
Breakeven distance
Smaller - BTC needs to move less
Larger - BTC must move further to profit
Best used when
Moderate but significant moves expected (3% to 8%)
Extreme move expected, lower cost priority
For major macro events where BTC regularly moves 3% to 8%, the straddle tends to be the more reliable structure because the breakeven is closer to the current price. The strangle makes more sense when you expect an extreme move but want to reduce the upfront cost.
Why do CPI releases and macro events create ideal straddle conditions?
The Consumer Price Index (CPI) is a monthly measure of inflation in the United States. When CPI data comes in higher than expected, markets interpret it as a signal that interest rates may stay elevated, which historically puts downward pressure on risk assets including BTC. When CPI comes in lower than expected, markets interpret it as a signal that rate cuts may be closer, which historically drives BTC higher.
The direction of the move depends on the number. The existence of a significant move is close to certain. CPI has consistently been one of the highest-volatility events for BTC options markets over the past three years. The same applies to Federal Reserve interest rate decisions, Non-Farm Payroll releases, and major regulatory announcements such as Bitcoin ETF rulings.
These events share three characteristics that make them ideal for a long straddle:
Why macro events suit straddles
A known date and time. You can plan the trade in advance and enter before IV rises.
A binary or near-binary outcome. The market moves one way or the other depending on a single data point. There is no ambiguity about whether an event occurred.
A historically significant magnitude of movement. BTC regularly moves 3% to 8% or more on major CPI and Fed days. For a well-structured straddle, that is often more than enough to cover the combined premium of both legs.
How do you structure a long straddle on BTC?
Setting up a BTC options straddle requires three decisions: the strike price, the expiry date, and the position size.
Choosing the strike price
For a long straddle, the strike price should be at the money (ATM), as close as possible to where BTC is currently trading. ATM call options carry delta near +0.5 and ATM put options carry delta near -0.5, giving the straddle a combined net delta close to zero. This confirms the position has no directional bias and is positioned to profit from movement in either direction.
If BTC is trading at $100,000, you buy the $100,000 call and the $100,000 put. If the nearest available strike is $99,000 or $101,000, use whichever is closest to the current price.
Avoid OTM strikes for a straddle. A cheaper premium sounds attractive but the breakeven move required becomes much larger, and the probability of a profitable outcome falls significantly. The strike is the fulcrum of the trade. BTC needs to move away from it by more than the total premium paid for either leg to move in the money.
Choosing the expiry
The expiry should be close enough to the event that theta decay does not eat the position before the event occurs, but far enough that you are not holding the trade into the final day before expiry where gamma risk becomes extreme.
Expiry guide for CPI and Fed events
Event two to four days away: use an expiry one to two days after the event. This keeps theta low in the lead-up and gives the position time to react to the announcement.
Event one to two weeks away: consider a weekly expiry that captures the event date.
Avoid same-day expiries unless you are an experienced trader. Same-day expiries create extreme gamma exposure where small moves within hours can wipe the position entirely.
European style options: Most crypto options, including those on Paradex, are European style and can only be exercised at expiry, not before. In practice this does not affect a straddle significantly because you will typically close both legs by selling them before expiry rather than exercising them. You capture the profit from the premium expanding as BTC moves, then exit.
How do you calculate the breakeven on a straddle?
The breakeven calculation for a long straddle is the simplest in all of options trading.
Breakeven = Strike Price +/- Total Premium Paid
Breakeven worked example
BTC is at $100,000. You buy the $100,000 call for $1,200 and the $100,000 put for $800. Total premium: $2,000.
Upper breakeven: $100,000 + $2,000 = $102,000. BTC needs to be above $102,000 at expiry for the call to cover both premiums.
Lower breakeven: $100,000 - $2,000 = $98,000. BTC needs to be below $98,000 at expiry for the put to cover both premiums.
If BTC closes at $107,000, the call is worth $7,000. Subtract the $2,000 total cost: profit is $5,000.
If BTC closes at $94,000, the put is worth $6,000. Subtract the $2,000 total cost: profit is $4,000.
If BTC closes exactly at $100,000, both options expire worthless. Maximum loss: $2,000 - the full premium paid. Unlike short options strategies, a long straddle has no additional margin call risk beyond this cost.
The key question before entering any straddle is whether the expected move is larger than the breakeven distance. If BTC typically moves 4% to 6% on CPI days and your breakeven requires only a 2% move, the straddle has a historically favourable setup. If your breakeven requires a 7% move but BTC historically moves 3% on this event type, the premium is too expensive for the expected outcome.
Why does entry timing matter so much for a straddle?
Implied volatility rises before major events. As CPI day approaches, traders buy options to position for the anticipated move. This demand inflates IV, which inflates the premiums of both the call and the put legs of your straddle. The closer you buy to the event, the more IV has already risen, and the more you pay for each leg.
Because both legs of a straddle are long options, the position carries additive positive vega. Both the call and the put benefit from rising IV simultaneously. This means a straddle entered before IV has risen can show a paper profit from vega gains alone, before BTC has moved at all. It also means IV crush after the event hits both legs at the same time, not just one.
IV crushes immediately after the event. The moment CPI data is released, uncertainty resolves. IV collapses. Even if BTC makes a significant move, the falling IV reduces the value of both options simultaneously. If the move is not large enough to overcome the IV crush, the straddle loses money despite BTC moving in one direction.
The ideal entry for a long straddle options strategy is before IV has risen significantly, typically two to five days before the event.
Entry timing - same event, different outcome
Early entry (3 days before CPI): IV at 45%. $100,000 call costs $900, $100,000 put costs $700. Total premium: $1,600. Breakeven requires a 1.6% move from $100,000.
Late entry (day before CPI): IV at 75%. Same call now costs $1,400, same put costs $1,100. Total premium: $2,500. Breakeven now requires a 2.5% move.
BTC moves 2.2% after the announcement - a $2,200 move from $100,000.
Early entry result: $2,200 move minus $1,600 cost = $600 profit.
Late entry result: $2,200 move minus $2,500 cost = $300 loss.
Same event. Same BTC move. Same direction. Different outcome entirely because of entry timing.
Timing is not a minor detail in a straddle. It is often the difference between a winning and a losing trade on the same event.
How do you place a long straddle trade step by step?
This is how to trade crypto options using a straddle on Paradex, from opening the chain to having both legs live. The straddle requires placing two separate orders: one call option and one put option at the same strike and expiry.
2Select your expiry tab. Choose the expiry that falls one to two days after the event you are trading. For a CPI release on a Wednesday, a Friday expiry works well.
3Find the ATM strike. Look for the strike price closest to where BTC is currently trading. This single strike will be used for both your call order and your put order.
4Check the IV column. Note the current IV level for contracts at your chosen strike and expiry on the options chain. If IV is already elevated compared to recent days, your breakeven distance will be larger. Consider whether the expected event move still justifies the entry.
5Calculate your total cost before placing anything. Note the ask price of the ATM call and the ask price of the ATM put separately. Add them together. This combined figure is your total premium, your maximum loss, and the distance BTC must move from the strike to break even.
6Calculate your breakeven levels. Upper breakeven: strike price plus total premium (e.g. $100,000 + $2,000 = $102,000). Lower breakeven: strike price minus total premium (e.g. $100,000 - $2,000 = $98,000). If the required move feels too large for the event, wait for a better setup.
7Use the payoff chart. On Paradex, the payoff chart shows your profit and loss at every BTC price level at expiry. Before placing either leg, use it to visualise exactly where the trade makes money, where it breaks even, and where it loses the full premium.
8Place the call leg first. On the calls side of the chain, select the ATM strike at your chosen expiry. Enter your quantity. Review the order details: strike $100,000, expiry Friday, direction buy, type call. Confirm the order. The call leg is now live.
9Place the put leg immediately after. Switch to the puts side at the same strike and expiry. Enter the same quantity as the call leg. Review: strike $100,000, expiry Friday, direction buy, type put. Confirm the order. You now hold one call and one put at the same strike and expiry. The straddle is fully constructed.
10Verify the combined position in your Greeks panel. Your ATM call carries delta near +0.5 and your ATM put carries delta near -0.5, so net delta should be close to zero. This confirms no directional bias. Your total theta shows the combined daily cost of holding both legs. Your total vega shows how much the position gains for every 1% rise in IV and loses for every 1% fall.
11Set your exit plan before the event. Decide in advance at what point you will close the position. Write it down. The best time to make decisions in a volatile market is before the volatility arrives.
Try the setup before committing real capital. Open the Paradex options chain, find the next major economic event on the calendar, pull up the ATM strike, and note the combined call and put premium. Calculate your breakeven and see whether the historical move for that event type covers it. You can do this entire exercise without placing a trade.
Placing the straddle is only half the trade. Managing it through the event is where most of the real decisions happen.
Before the event
Monitor IV as the event approaches. If IV rises sharply in the days before the announcement, your position may already be showing a paper profit from vega gains. Some traders take partial profit at this point by closing the call leg or the put leg, effectively converting the straddle into a single directional bet on whichever option they kept.
Immediately after the announcement
This is the most critical moment. BTC will move and IV will crush simultaneously. The value of your winning option (the call if BTC rallied, the put if BTC fell) will be increasing from delta gains while being reduced by vega losses from IV crush. Move quickly. If BTC has made a significant move, sell both the call and the put within the first few minutes after the announcement. Waiting allows IV crush to continue eroding the value of both options.
If BTC barely moves
If the announcement causes less movement than expected, both the call and the put will lose value from IV crush. Close the position quickly to minimise losses. Do not hold through expiry hoping for a recovery. If the event has passed without a large move, the thesis for the trade is over.
If direction becomes clear
If BTC makes a decisive initial move in one direction and you believe the move will continue, close the losing leg immediately to eliminate its ongoing theta decay. For example, if BTC rallies hard, sell the put at whatever value remains. Let the call run. This converts the straddle into a single-leg directional position and removes the drag from the option working against you.
Where can you trade a long straddle on bitcoin options?
To execute a straddle effectively, you need a platform with two things: genuine liquidity at the ATM strike so both the call leg and the put leg fill at the expected price, and a clear interface that shows you the combined Greeks and payoff of the full position before you confirm either order.
Paradex is built by the team behind Paradigm, the largest institutional options liquidity network in crypto. That institutional depth flows directly into the Paradex order book, which means your call and your put both fill at competitive prices rather than sitting unfilled in a thin market. For a straddle, where both legs need to execute cleanly and quickly before the event moves IV further, liquidity is not optional.
The one-click order builder makes placing each leg straightforward. The payoff chart updates in real time as you add each leg, showing the combined profit and loss profile of the full two-leg position before you confirm the second order. The live Greeks panel shows your combined delta (close to zero for a well-constructed ATM straddle), your total theta (the daily cost of holding both legs together), and your total vega (your sensitivity to IV changes, which is the primary driver of the trade's value before the event).
Paradex is available on desktop and mobile. In a strategy where closing both legs within minutes of a CPI announcement can be the difference between capturing the full gain and watching IV crush erode it, the ability to act from anywhere is a meaningful practical advantage.
What is the one thing to remember?
The long straddle does not care which way BTC moves. It only cares how far.
That single reframe changes how you think about macro event trading entirely. You are not trying to predict whether CPI will beat or miss expectations. You are not guessing whether the Fed will be hawkish or dovish. You are making a much simpler bet: that the market's reaction to the number will be large enough to cover the cost of both legs.
Enter before IV rises. Size the position so the total premium fits within your risk tolerance. Calculate your breakeven before you place a single order. Have your exit plan ready before the announcement drops.
Place your first long straddle on Paradex. Open the BTC options chain, find the ATM strike for your chosen expiry, check the combined call and put premium, and calculate your breakeven before you commit.

A long straddle is a non-directional options strategy where you buy a call and a put at the same strike price and the same expiry date. It profits when the underlying asset makes a large move in either direction. The maximum loss is the total premium paid for both legs, and it occurs if the asset stays near the strike price at expiry.
The best time to buy a long straddle is before implied volatility has risen, typically two to five days before a known major event such as a CPI release, Federal Reserve decision, or major regulatory announcement. Entering after IV has already spiked means paying a higher premium and requiring a larger price move to break even.
The maximum loss is the total premium paid for both legs combined. Unlike short options strategies, a long straddle has no additional margin call risk. If BTC closes exactly at the strike price at expiry, both options expire worthless and the full premium is lost.
Upper breakeven equals strike price plus total premium paid. Lower breakeven equals strike price minus total premium paid. For example, if BTC is at $100,000 and the combined call and put premium is $2,000, the upper breakeven is $102,000 and the lower breakeven is $98,000. BTC must close above $102,000 or below $98,000 at expiry for the position to be profitable.
A straddle buys both a call and a put at the same ATM strike. A strangle buys an OTM call above the current price and an OTM put below it. The strangle costs less because both legs are out of the money, but it requires a larger price move to become profitable. The straddle has a higher upfront cost but a smaller breakeven distance, making it more suitable for moderate but significant moves like typical CPI or Fed reactions.
Because a long straddle carries positive vega on both legs simultaneously. When implied volatility collapses after an event resolves, both the call and the put lose value from that collapse at the same time. If BTC moves 2% in one direction but IV drops 30 percentage points, the vega loss on both legs can exceed the delta gain on the profitable leg. This is why entering before IV has risen and exiting quickly after the announcement are both critical to the trade's success.
