Max Loss Per Trade %
What it does
Sets the most a single trade may put at risk as a percentage of live account value, used when the mode is percent. The ceiling recomputes every cycle from the broker NLV, so it scales with the account. A candidate above it is skipped, not resized down to fit.
When to change it
Adjust when you want per-trade risk to track account size automatically. Be aware of the quiet failure mode: if no account value resolves, this check is skipped entirely and only the allocation cap guards the entry. If that concerns you, use dollar mode instead.
Safe range
1% to 3%. Above 3% a short run of losers can meaningfully dent the account, which defeats the purpose of a per-trade cap.
Example
Set to 2 on a $50,000 account and the cap is $1,000, so a $700-risk condor passes and a $1,200-risk spread is skipped.
