These functions can be used in Results and/or Strategy formulas to drill down into the list of trades from the current test and calculate a few basic statistics about them.
Unlike the Indicator and MultiBar functions, the optional Count argument in these functions is a count of closed trades, not a count of bars or dates.
If the optional third argument Symbol is specified, Count applies to closed trades for that symbol.
Here are some example use cases:
Most often the items that you'll want to reference within these formulas will be Trade Record Values.
When called from a Strategy Element formula, Bar Data Values can also be referenced.
When called from a Results Section formula, only the Trade Record Values are available.
If you need to reference a tradespecific data value such as an ATR indicator, you can calculate it during the test using EntryTradeValue or ExitTradeValue and then access it for the formulas below using T.ValueIn or T.ValueOut.
The following trade statistics functions are provided:
TradeStatAvg  the average of trade record values for the most recent N trades or for all trades
TradeStatMax  the largest of trade record values for the most recent N trades or for all trades
TradeStatMin  the smallest of trade record values for the most recent N trades or for all trades
TradeStatStdDev  the standard deviation of trade record values for the most recent N trades or for all trades
TradeStatSum  the sum of trade record values for the most recent N trades or for all trades
