Apex: lot cap math for gold volatility days

[LondonScalper]

Apex lot-cap math on gold volatility days is arithmetic before it is psychology.

I take the firm’s daily loss constraint, a realistic XAU stop after spread, and I solve for a lot that still leaves room for being wrong twice without drama. On quiet days the number looks conservative. On volatile days it looks like the only adult in the room.

Math I actually do

• Daily max loss in account currency
• Stop distance in price × value per lot
• Buffer for slippage so the "max" is not theoretical

If the allowed lot is tiny, I either trade a cleaner invalidation or I stand aside. Forcing personal-account size onto Apex gold is how volatility days become rule days.

What formula or shortcut do you use for gold lot caps on Apex when the metal is running?

I keep a one-line example in the journal: vol day lot equals min of normal and daily_max divided by stop times value plus buffer. When the metal is loud, I want arithmetic in front of me, not a vibe about courage.
