I suspect that the correlation is not as good as you suspect, reflecting the difference in portfolios. Plot the relative performance of the two or the correlation between them and see if they are strongly correlated.

I'm a new user of Amibroker and am spending weeks converting my old Window on Wall Street simple formulas to Amibroker. It's been a steep learning curve, but here is my problem. An example: When I take a simple strategy, such as a MA crossover system and run it with a mutual fund, say a Latin America fund, I'll get profit up 300% in 7 years, as an example. I'll then take a very similar ETF, that has a 99% correlation to the mutual fund and has the nearly identical buy & hold return as the mutual fund, but the performance for the ETF may be half or even only 1/3 of what the mutual fund was. I use Yahoo Finance's EOD data, so could that be the problem? Maybe the stops I have set up are based on more than EOD close. I've tried changing the buy price settings every way possible (Open+1, Close+1, Average+1...etc.), but I can't get good numbers. The only change I can make gets great results, but is unrealistic: Open+0. Amibroker support says that isn't right for EOD data anyway. I'm hoping my settings are off or some formulas (like stochastics) are based on more than close and that could be my problem. However, even the formulas that are 100% based on close are showing poor results. Any advice? Aren't ETFs going to perform better due to intraday trading?
