Hello fellow forexers
I have what may be a silly question, but it seemed slightly in depth for the beginner section. Please feel free to move this if I'm wrong.
I'm working on an EA to perform a very simple string of trades that sometimes extends into the early morning hours. From visual backtesting and metatrader's (admittedly horrible) backtester it works like a charm, but now dealing with live data for the past couple months it has had some challenges that I need to fix (dealing with requotes etc) that appear to require me to change the actual strategy rather than simply fixing programming bugs.
So here's the question(s): at what point am I 'curve fitting', and at what point am I simply fixing unforseeable issues that have cropped up during live testing? Am I improving the strategy, or dooming the strategy to never work by being too focused on yesterday's data? And I suppose the most important question, is it even possible to 'curve fit' to live data, or is curve fitting just something people do to sell their new 'super wonder gonna-make-you-rich EA' on ebay with a killer backtest graph?
Many thanks in advance!!
