Just go through the trade history and times. If a new trade is not opened in the same symbol when another is at a loss, it is not a martingale. Otherwise it is. I dont understand how lotsize helps.
On a martingale account the Lot size will prove beyond doubt that martingale is used.
Hence why Lot size helps. Now you understand.
How exactly will it prove anything? Please be specific with a real example where you can't say whether a system is a martingale or not without the lotsize.
Sorry to intervene, but I never understood this debate, martingale is to increase lots, to recover from a loss, the martingale always, mathematically loses pips, can give you money, but never pips, so it is very simple to detect, I honestly do not understand the debate...
Risk comes from not knowing what you're doing.
