I’ve been trading Nifty weekly expiries for a while and found myself frustrated every time I wanted to quickly stress-test a trade setup, specifically checking what happens to an Iron Condor if IV spikes 8% before expiry.
Sensibull does this but felt like overkill for a quick pre-trade check. So I ended up building my own calculator: Get the free version at getconvexity.com, covers payoff charts and max loss for the basic strategies. There’s a Pro version too with full Greeks and a 49-scenario IV stress test matrix if anyone wants to try it.
Curious what others here are using for pre-trade analysis. Do most people just eyeball it, or is there a tool I’m missing?
