Bogie-NN-v8 is different all right, at least in the sense that as a commercial product, it has a total disregard for any other EA that seems to be running on the same platform - see below how it closed dozens of orders from another EA, even though different magics and currency pairs were involved! Unacceptable...

deleted....

Yes, I noticed that as well, but I'm sure many think that dswk was after somehow copying Bogie's indicator, when in fact the opposite is true - Bogie's indicator is a renamed public domain EA!

btw, I think the Bogie developer included NN's simply to increase sales by jumping on the NN band-wagon. The indicator he copied was written back in 2003 as far as I'm aware so it definitely isn't 'cutting-edge' by any means. Also, 'retraining' the indicator is fairly trivial, I'll do it and post it when I get a chance - though, one would have thought that Bogie's indicator is already retrained (for EURUSD I'd suspect) so just rename that and try that!

Finally, the 'open-source' EA that dswk posted is a straight copy from the NN tutorial site, and it doesn't work as is - at least I couldn't get it to work. And it also needs to have the indicator retrained to be of any use. Personally, I think FANN is the way to go - no need for Cortex, and it now has MT integration. I have only recently resolved to learn how to use it, so I don't know much more about it yet...

Here's the result i've got from the "open source" version, with the open source indicator.
Init Capital : 10K$
First test : Without MM. 0.1 lot, 6 months (Jan-Today). Buy/Sell trigger at 54/74, SL 200 TS 170.
Second test : Without MM. 1 lot, 6 months (Jan-Today). Buy/Sell trigger at 54/74, SL 200 TS 170.
not bad...

@dswk - I stand corrected - I was entering fractional values for the Buy/Sell triggers which was the problem! Thanks!

PS - did you retrain the indicator for a particular currency before posting it?

The training of the NN is not as easy as it may sound... It involves using the cortex software.. I would suspect a re-trained version could prove to be better then the outdated version we currently have..

Hmmm, I stand corrected again! Having just spent an hour with Cortex (which is pretty easy to use), I find that while training an network is easy, there is no way to export it from Cortex - I'm pretty sure this is one of the options that is missing with the Shareware version, along with the inability to run scripts (which sucks!)...

btw, interesting exercise - while the opensource EA does seem to produce good recent results for EURUSD H1, running a test on all available data with a monthly chart open, you should notice that the equity curves follows price perfectly - when EUR is appreciating, it makes money, and when it was falling it lost money. This is further borne out when you compare the Buy/Sell percentages. Considering the EUR has been appreciating almost continually for several years now, I reckon its apparent edge is an illusion...

This will be fixed by optimizing the buy/sell levels.. As eur/usd begins to fall the sell level should be closer to the 50 level.. The optimizer in mt4 would give the best results for the more recent market..

This is why i said the strategy tester should be run one month at a time after a 3 month optimization.. this would roughly produce the most accurate buys/sells for the market/upcoming market..

Running live i would probably re-optimize these values every weekend..

...
That's the way to use it ...

I have already done an optimisation for the period Jan '07 -> present - the optimisation results look little more than random to me!

The 'kicker' as far as I'm concerned is that the two differently named NN indicators that I have in my library all use the same weights that the author of the NN tutorial generated back in 2003. In fact, considering that Bogie's indicator generates an identical output signal, it looks increasingly likely that this also uses the same NN weighting values! So optimising Buy/Sell levels for 2003 weightings is pretty much a waste of time (imo)...
