Uses fixed fractional position sizing based on account risk %.
💡
A long option means you buy a call (betting the stock goes up) or a put (betting it goes down). Your maximum possible loss is exactly the premium you pay — nothing more.

Premium is the price per share shown on your broker (e.g. $3.50). Each contract covers 100 shares, so 1 contract costs $350 total.
Spread Details
$

Enter the max loss your broker shows for this spread. For a bull call spread, this is the net debit you paid × 100. For a credit spread, it's the width of the strikes minus the credit received × 100.
