This is just an example to demonstrate the ability of a MT4 Expert Advisor (non-scalping EA) to produce great results on the MT4 Strategy Tester. These results, with same MT4 EA and settings, are not producible on a forward Demo or Live Trading account.
Why? Lack of Strategy Tester to have full tick simulation of Bar Bid/Ask INTERPOLATION. I personally believe that without this INTERPOLATION, majority of EAs with entry/exit points and Indicators based on Bid/Ask will not have Strategy Tester results match up with demo and Live trading.
I have come here as I was curious about an idea that I was exploring myself... and I wondered why a good backtest won't
necessarily forward test well... albeit my EA was more of a scalper that the original poster's EA.
idea when backtested for 3 months, went from 10k to 18 million, and
only stopped exponential growth 3 month into it as it hit MAXLOTS half way through the backtest....
Yet when I tried it FORWARD TESTING on a LIVE or DEMO account, it didn't perform at all like this.
I didn't mean to revive a 3 year old post however I wanted to add to the body of knowledge.
this case, I had worked on an idea just as they added spread into
backtester, and it was before I reaslied spread was in points... silly
mistake, and a funny sidetrack... but interested results...
idea does work until spread is 10 points (1 pip), however I looked into
brokers who have zero spread and commissions only, or fixed spread, and
the commission exceeded the profits, as this EA takes small profits...
My profit factor was only 617.80 and it was a scalper (and low modelling quality), however it was a 3 month test, not 3 year.
Left wondering if INTERPOLATION is the problem too.
So I guess this is another example of a holy grail backtest, that is not usable live :(
