Net Trap EA - variant backtesting

Hi

I'm going to run the EA through the Metatrader Strategy Tester with a selection of the NT variants. The initial test period will be 01/01/2010 to 19/10/2010. I don't have a lot of faith in the Strategy Tester in terms of absolute results BUT I do think it's a reasonable tool for comparing the effects of the various options.

I will post each test report separately, along with an associated MT parameter "set" file, which allow that variant's parameter settings to be used for the EA.

Cheers,
Greg

Re: Net Trap EA - variant backtesting

SpindriftUK started this thread And here's one I prepared earlier

Attached are the report and set file for VNT. Just realised I can't post the .set file

Ok, I have attached the set file as vnt.txt. If you want to use it, rename it to .set and place in your experts/presets folder. You can then use the Load button in the EA parameter input dialog to use it.

The little graph is supposed to be embedded in the report but for some reason, it gets lost. Have attached it separately.


Cheers,
Spin

Re: Net Trap EA - variant backtesting

SpindriftUK started this thread Given that RH has just re-opened the doors on Net Trap, I thought I would see how the EA with VNT parameters set would perform over the same period that RH is quoting results for. Not surprisingly, the results are widely different from month to month, with the EA's results for June, especially, being very suspect. I had a lot of trouble getting June's history data and I have a feeling it has probably been constructed on a best guess basis

Anyway, what was surprising was that the EA's final profit for that 16 month period came out very close to RH's published results - $19179 at $10 per pip against RH's £19670 at £10 per pip. I have attached a spreadsheet of the EA's results - read into it what you will!

I did an optimisation exercise for the period 01/07/2010 to 30/09/2010 - 25 passes with stop loss varying between 30 and 70 in steps of 10 and take profit varying between 10 and 50 in steps of 10. I have attached a screenshot of the results (SLPipsS was set the same as SLPipsB for the purpose of the exercise).

Cheers,
Spin

Re: Net Trap EA - variant backtesting

SpindriftUK started this thread Going back to the "year to date" tests, I have attached the results for VNT plus RH's advanced tactics: ant1- Safety Net Plus and ant2 - Safety Net Extension. Also attached are the parameter files for the EA for each option.

Cheers,
Spin

Is this risk-adjusted (i.e. 3% at risk divided by number of pips) or at the same lot size?

Almost the same lot size I allowed the EA to calculate a percentage but forced it to use the same bank every time. I think the slightly different lot sizes are the result of rounding the 5 decimal point OHLC values prior to adding the 50 pip target during the calculation of open price.

Btw, I notice that I didn't specify the parameters correctly to simulate ANT2. I should have set the lock-in pips to -30, as that would keep the stop loss the same as originally set. As I've got it, stop loss will be moved to break even. I will run it again and hopefully edit the post, although I notice I can only do the edit if the post is less than a day or so old.

Spin

Thanks Spin though I am afraid I don't quite follow: don't you just divide the bank by the SL so that the candle readings have no bearing on the calcuation of the lot size?

You're right, of course. I've obviously been at this too long today

I'll take a look at why there's a slight variation in the lot sizes through the back test.

Time for a beer, methinks!
