the trade system in this case could have been any long/short trade system.
I think the winners/loosers ratio is only applicable to a limited amount  of
trade systems and does therefore provide only limited confidence about the
expectation of trade systems.

Other ratios like LiquidationPnl / Trades make more sense, or for example, a
curve marked-to-market values of the position once a trade occurs.

Another aspect is also the definition of a trade, i define, and i think
that's also the mainstream definition a trade as a transaction. What you
call a trade completion is something i know as a roundturn (buy and sell).
The term round turns is  not applicable to pyramidizing systems, i think.


Kind regards,
Ulrich
