Too good to be true

Dear All,

I just made an EA and backtest with 90% quality data.
Success rate about 85%, maxmium drawdown is 4%.
It turn a 10000 account into 10000000 in 1 year (Backtesting with 2004, 2005, 2006 and 2007 Jan - May)

I am working on a 1H and 5M tf. and I use function iClose with shift 0. I check that the order will trigger in the current bar not waiting for the close of the bar. The result is too good to be true, I just wonder if any possibility that the EA is accessing future data in backtesting? so that it provides such a fantastic result.

Of course, I will try to forward test this week.

Thanks

Do any of your iclose or ihigh or ilow and such statements have a negative number as the reference at the end of their fields?

If so they are definitely looking into the future.

Like iClose(NULL, PERIOD_H1, -1)

No, I use iClose and iOpen with shift 0
like this iClose(NULL, PERIOD_H1, 0).
I just wonder, in the current bar, in real life, the bar is not finished yet.
But in backtesting, will I get the Close of the bar before the bar end?

Oh! the thread moved to Beginner Q&A,
It sound a simple question to all experts. Is that a known problem of MT4 backtesting?



Thanks

Just get a feedback from other post
iClose[0] return current bid in live and backtesting.

What exacty is backtesting?

using history graphics and compare them with current graphics and thus find a trend?

Does MT4 demo have that feature?

Probably a separate thread entirely, but in short, it's a method of using historical price data and trading a system as if it were "live". Computer programs can obviously do this very quickly, so what ends up happening is you get a report of how well your system did against the historical data.

As you may or may not have figured out, since the data is rarely tick data AND you can't predict how your broker would have reacted while trying to trade during the time you placed your trades, backtesting is NOT an accurate representation of how you would have actually done NOR is it an accurate representation of how you will do in the future. What it IS valuable for is getting a general idea of how close to success you could be coming to given a particular set of circumstances.
