Does the market need to move slightly further for spread straddles vs doing binary strangles when setting similar Take Profit levels?
Market movement for successful Strangles vs Straddles
Since Spreads basically move tick for tick, I want to say yes the spreads will have to move further in most cases. Keep in mind that a strangle has a better chance at a complete loss vs the Spread straddle.
Your best bet would probably be to use how you are taught to choose the binary strike prices in the OTM Mastery Course and that will help you make a more informed decision.
