kenel the drawdown you hit with that is near 27% of net a bit toppy upto 25% is tolerable some say, but the lower the better maybe, thats the puzzle for people to explore, modern day alchemy, keeps your brain ticking, but again its down to individual risk tolerance, ive been working on dollar yen over 13 years data long and short side drawdowns at 10% both sides , still working on it averages 13/1500 pips a year long and short. but thats based on 13 years data.
you can get boggled and like you say too close and immersed sometimes to reason without bias maybe..
some advocate walking your system backward/forward over a data period, say 5 years, then walk it forward the next five, etc, depending on how much data you can access..
leave inputs the same etc, see if there is any significant difference in ratios that may warrant a rethink.. if you used money stops you may need to consider allowing for a range expansion over the years if testing the stock indexes spanning a decade or 2 .
Im far from expert but managed to locate supercharts EOD software which was misplaced in another lifetime, constantly questioning the markets based on past activity rings alarms for some, but the price bars represent human behaviour, and thats not likely to change for the next few hundred years anyhow
when ive finished mine i'll chuck it up for critique from the perhaps more knowledgeable to see weaknesses/ strengths, few weeks off yet though.. need recent data last 3 years back end of day, CME dollar/yen or 15 years of end of day for the same pair, need it ASCII .txt struggling to find it for supercharts since they stopped supporting it.. baahhh..
anyone know of a source ? not too concerned if its cme spot or elsewhere just struggling for EOD spot.. historical downloads. I realise its 24hr with the fx, the system im working on has a roomy stop pip wise but not constant. so i assume its doable regarding overnight price action around the world, london or new york close would be ok, maybe both.. ?? still searching for that info...
