another idea is to show for each trade the max negative pips and max positive pips since the position was open ... of course since everyone here is using a different broker that would be an estimate since you'd have to choose probably one price feed for simplicity ... (zulutrade shows the max negative and positive while the trade was open)

also maybe some summary index showing a avg max neg vs avg max pos for all positions ... that would show systems that use high SL with tiny TP

One of my strategies shows negative pips but it has nothing to do with martingale, it's sometimes a matter of aggressive MM.

of course if you place a trade with 0.01 and loose 1000 pips and if you place a trade with 10 lots and win 10 pips then you'll be pip negative but cash positive ... counting pips makes sense if you count the same sizes of the positions ...

Another issue with martingale is that when you open a trae and then close part in history it appears as bunch of trades.
Let's say you opened 12 lot's @1.0, then closed 4 lots @ 0.9980, and then 8 @1.0020 - it looks like martingale but is a proper money management...

Trades should only be flagged as martingale or excessive averaging down, if a cluster of trades is opened that exceeds 5 , 6 or some arbitrary % of equity. Opening 30 micro lots isn't the same as 30 mini lots within a 5min bar. Thus staff should put the arbitrary % to a vote or allow user input on a webpage to set some arbitrary limit. You as an evaluator of a system should be allowed to set your own arbitrary martingale or averaging down limit, depends on the server load really.

Another issue would be to flag trades that remain in excessive negative equity for to long a period lets say two days. One needs to differentiate between random market flux and trading insight. If the individual trade draw-downs are to large and period in negative equity is long an arbitrary score should be assigned to a trading system. Collective2.com has a grading index. We should agree on some method of scoring a system. It should not though excessively penalize a system, lets say the system only had a 50% exposure three months ago for one day then the scoring system should 'soften' such negative input etc, because traders gains new insight as time moves on.
