A different lot size by itself is not automatically martingale. Many traders using fixed percentage risk will use different lot sizes because the stop-loss distance changes with market structure.
The rule is focused on realised-loss recovery behaviour on the same symbol. It looks at whether a trader closes a position, or group of positions, at a cumulative realised loss and then opens a new same-symbol position, or group of positions, with cumulative volume increased by 100% or more from the reference volume.
Example: if a trader closes EURUSD at a cumulative realised loss with a total closed volume of 1.00 lot, the next same-symbol cumulative open volume must remain below 2.00 lots. Opening 2.00 lots or more on EURUSD would constitute a breach.
If a trader uses a different lot size because the setup has a different stop-loss distance, that does not automatically create a breach. The issue is whether the trader is materially increasing same-symbol volume after a realised loss in a way that meets the rule threshold.
The sequence resets at 17:00 New York Time each trading day and at the end of each payout cycle. If the warning is based only on closed trades and no relevant open trades remain, it should clear after the reset. Any open trades are carried forward into the next trading day or next payout cycle.
