For every honest trader there are 100 charlatans able to build a trackrecord with good return and low DD , martingale is only one of the ways.
Charlatans were not trained to cheat EX RS LA but know very well how to cheat Return and DD.
Dishonest traders cannot cheat Time and experienced investors for long.With good forum this time of cheating can be very short.
Hidden risk will materialize sooner or later.That is why I recommend investors must wait until they can inspect DDs of their candidates.Than they can make an educated guess what they are risking by entering in such darwin and if they enter during next DD,they can calculate where to put reasonable Stop-loss order.
EX,RS and LA as well as Var algo can be cheated if there is will.
RS cheating is becoming popular right now with traders who wish to gain advantage over competition and trade constantly with VaR very close to 6,5%.
FSK was playing VaR like a violin with different technique and ultimately paid the price.
EX and LA can be cheated and are cheated with slicing your trades/positions.Now there is no need to cheat EX because D-score is not dependent on it as before.But cheating LA is useful to deceive investors who are trying to spot problematic discipline or martingale techniques.LA is also inaccurate-many times there are missing trades right when you need to see them.
Just wait for DDs and long track-record.
New D-score has good philosophy but it is so badly calibrated that it is possible to attain very good D-score with 1-year 'high Return' track-record or with bad trackrecord that is 3 or more years old. Darwinia winners show this clearly.You can also cheat D-score by migrating account from somewhere else or by not trading for prolonged period and thus artificially make track-record longer.
