How many of you blew a SPY options account because of position sizing?

I’m noticing something common with SPY traders (including myself).

It’s not entries.

It’s not strategy.

It’s oversizing.

Taking 20–30% risk per trade without realizing it.

I built a simple risk control sheet that:

* Forces position sizing

* Caps daily max loss

* Shows drawdown recovery %

* Simulates compounding realistically

Curious — would something like this actually help people here?

(I will drop the early access link if anyone is interested .)
