newdigital, could you be more specific about why trading at the Ask and Bid (bar 0) is, 'cheating' so to speak?
Attached are the equity curves of one of my Scalpers (10pip, 1:1 r/r) that shows spectacular results in Backtests but performs absymally when forward tested so it clearly is not profitable.
What I want to know is why exactly, so I can stop wasting time on stuff that does not work in reality.
Also, one of the 'tell-tale' sign that an EA's results are bogus seems to be what happens during the last 6-9 months of the backtest - usually the equity curve turns down abruptly. This occurs with all of my 'profitable' EA's unfortunately and I have yet to hear a convincing reason as to why this happens - more specifically, why does an inherently unprofitable EA seem very profitable up until the final months of the test? Anyone who has been using Metatrader for a reasonable period will have noticed this last '6-9 month' problem - note that 1 year ago, you had the same poor results for the last 6-9 months even though this period now shows up as profitable in backtests.....
The idea that tick data gathered realtime over the poorly-performing interval is the reason doesn't stand up as it also occurs when Metatrader is freshly installed. Could it be that all the historical data, apart form the last 6-9 months, that the Brokers supplies is 'artificial', generated in much the same way that the backtester interpolates its tick data? Also, I found that running the same EA, settings etc. on different broker platforms produces almost identical results so the all seem to be supplying the same crappy historical data...
I should have more on this soon as I am in the process of getting my hands on 'quality' historical data.....
