Is this for real? 10k to 5mm in one year!

 
So I wrote one of my first EA's, it seemed to favor USDCAD, so I tweaked and tweaked until I got the attached results. Can this be for real or is backtesting just a way we lie to ourselves about potential results?
 

"I tweaked and tweaked"

Run it forward for the next month on a demo account and give us another report.

Be sure to remember to attach it next time.

 
over-optimization.
 
yes we'd like to see it, have another shot at sending it.

Back testing does have limitations, the main issues are:

1) Over-optimisation - i.e. setting parameters based on historical patterns that will never happen again - or more typically, missing a situation that results in a vicious drawdown that is lurking somewhere in the next week/month/quarter of upcoming data!

2) Metaquotes history data is a little 'kinder' to EA's than single-broker

3) Some EA types just dont backtest accurately at all - I dont pretend to know why. Most common situation is, "EA does great in back testing, bombs in forward". More rarely, an EA that loses on back testing will win well on forward...! These seem to be the EA's that retain price & win/loss data in complex arrays, working out S&R levels on the fly and trading between them - but again I cant explain the 'why' of this - just is!


Having said that, you have to start somewhere & opening a chart based on a backtest can reveal a pattern of why your EA is losing

I tried to attach the file, it is an htm, i put the file name etc in the 'attach file' box on the bottom, but it did not attach it. Do I have to press something besides 'Update' ? File size is 38KB

Maximal and relative drawdown is 96.38%?

Sounds awfully risky despite the amazing results...


And biggest position 590 LOTS? $5900 per pip?

Sounds quite unreal later on for a real live account...

Ya thats pretty unrealistic. hahah

 
Yup, forward testing on a demo is the only way to know how an EA "feels". I agree with previous comments, though... I wouldn't want to be on the hook with 590 lots open.
 
Never trade martingale systems. Very simple. Very true. Even if you have a statistical advantage to every trade taken in the martnigale and you do all sorts of account safety, eventually you end up on the wrong side of a string. Martingale systems just delay the loss, they don't help the balance long term.
