Really good backtesting for Dummies

Hi Backtesting Experts,

i am the dummy here so i will try to compile all the info that you experts provide this thread allowing other dummies to backtest their dummy EAs properly!

i have gathered here in the forum that 99% modelling quality is as good as it gets when it comes to MT4 backtesting. is this close enough to forward testing? opinion welcome.

first step is gathering enough tick data. here is my best lead at the moment:

this is where i am at!

i will post my obstacles as i overcome them and hopefully compile here some helpful info for anyone needing it.

before we get to dukascopy data here is one question if any experts are listening:

supposedly we can get up to 90% modelling quality with metaquotes data.

i went to tools / history center / GBPUSD 1M/ download

and i get data for only a one month worth of data. is this normal? my EA will run on 4h and 15m timeframes. i wanted to download like 5 years of 1m data to test it with good quality. is this possible only with the dukascopy data?

appreciate it!

Wannaberich,

I dunno about Metaquotes but I found FXOpen ECN pretty good for downloading data. I got something like 10 years data out of them at 90%.

Care to explain how you did that?

thanks

Same way you did with Metaquotes. I also used the MT4 period converter as a good measure, so drop it on the GBPUSD H4 & M15 charts.

sorry for being such a dummy but there is no option on the history center window to choose another provider for the data! at least i don't see one...

here is what i see

Ah, ok. No problem. I downloaded their platform and opened a demo account. From there you can download the data and if you really want you can export it to your own broker but they have lots of data and their spreads are ok, so I like to use them for testing.

got it.
