MultiCharts: Trading Software for Automated Trading and Backtesting

I am aware of MaxPositionProfit(PosBack) but I would rather need something like MaxPosTradeProfit(PosAgo, TradeNumber) to get the maximum profit per trade.
Does something like this exists?

Hello xyz,

There is no such pre-built keyword in MC.
But you can calculate it yourself by using PosTradeProfit.
Here are some more Strategy Position Trades keywords.
