Hi Gary,
Yes, I am aware that the EA was built based upon 4 digit brokers. I just wanted to document the problem for 5 digits, especially since some of the things cannot curently be compensated for in the external parameter values.

Hi llambert3 -

I could tell you the truth and say I put in the wrong defaults for the trading window in version 2.1.......but that wouldn't be any fun. Instead I think I'll blame it on a 'secret' test which you failed because you didn't notice it!

Regarding the continuing SL issue: the following is a quote from damonl from a few pages back (post #410) in reponse to our discussion about the SL:

"The spread should not be used when figuring short trades and short s/l settings. Only for the long trades...."

In post #458 our fearless leader...
Hey Gary, I'll get back to you on this.. late for work.

Hey llambert3 -

.... The change in code to fix the issue of the trades closing early was literally changing a "0" to a "1" in one line of code. This got rid of many of the +1/-1 trades. ....

Hi Gary,
Since 2.2, I now get it not closing an in profit trade at end of 1st (enrty) bar/open of 2nd bar. It does close them at the open of the 3rd bar now though, rather than at BE +1.

The effect of this is that you can hit the S/L on a short without the extreme of the entry bar being exceeded. This is because the close of a short trade is effectively a long trade and thus it should have the spread added.

In post #458 our fearless leader damonl writes:

"Honestly, I did all my testing by moving the s/l regardless of where it moved to. Even if it happened to be more than the s/l. Since this was the rule i stuck with it for testing."

OK, fair enough since this is more in keeping with the way it would be traded manually.
However, this means that when using the EA, you have no way of knowing or of limiting your maximum risk (i.e. lots x S/L) because the S/L can be increased based upon the extreme of the entry bar.
So I suggest limiting the Max S/L size by using the Money Management parameter Max_Stoploss.

I believe that trading is all about limiting one's risk.

Hi John -

For FXDD set the GMT offset to +2. Change the SL for whatever pair(s) your trading to the values in post #1 and then change the trading options to 'true' for those ones you want to test.

Gary
Thanks a lot Gary =)

Ok, Damon did say that, but I am not sure he meant it! We'll have to let him reread his post and reply. The only time spread should come into play is when the ask is the stop loss, which would be a short trade.

Hi Ian -

Thank you for your constructive feedback. Good comments and observation. If I understand correctly, you are suggesting that one could change the maximum stoploss value in the ea settings to the same value as originally set at the beggining of the trade (= SL listed iin post #1). In effect, never increasing risk beyond the suggested SL level. Right?

Hi llambert3 -

In manually trading this system originally I did the following:

For a buy -
Enter 1 pip + spread above the Close of previous bar;
SL = per post #1;
At the close of the entry bar and profit < 0, move SL = 1 pip below Low of the entry bar.

For a sell -
Enter 1 pip below the Close of previous bar;
SL = per post #1 + spread;
At the close of the entry bar and profit < 0, move SL = 1 pip + spread above the High of current bar.

So.....I think we're on the same page?!

damonl - did you mean it??

Hi Ian -

You are correct. The closing was changed to reflect the following statement by damonl in post #410:

"The trade should also not close at b/e +1 after the close of the first bar unless the 2nd bar closese at b/e +1. "

As I mentioned to llambert3, it is possible to keep the close in version 2.1 as an option so the two closing variations could be tested. I'm waiting on feedback from damonl.

Thanks for the comments.

Yes, the only reason for the initial S/L is that you don't know how big a 'pull' there will be on the 'catapult' and its not good to go into something like an interset rate decision or NFP with no stop.

When trading manually you should be aware of such things, but an EA trades blindly. Thus it is good to limit the potential loss. To me the already existing parameter called Max_StopLoss is better named for this purpose than is the parameter called Stoploss.
Currently the parameter Max_StopLoss is only used in the lotmaker routine,
which is not of much use for test purposes - though very important for a live trading EA.

Gary,
What I was saying was the B/E +1 problem is fixed, but that now it doesn't close when the entry bar closes in profit. Instead it will wait until the next bar closes in profit (or the one after that etc.).

It is simple, buy in a blue slingshot bar if the HMA line is blue and sell in an orange slingshot bar if the HMA in red. Set the HMA Period to 8.
My results,using only this filter and only 30 min tf, are;
monday: +80
tuesday: +287
wednesday: +17
thursday: +165
friday: +251

The MM: SL like in post 1 (change only USDJPY to 30) and to take profit for this results I did not change the SL and waited until a bar closed in profit or BE or hit this SL. Sorry for this confusion.

Best Regards

Hi Dibanos -

How are you specifically using the HMA to signal a trade?

hi,

I don't know if this helps at all, but here's my statement for today.
it's terrible...
(2.2, all single filters and triple filter on, M30 + H1, all 5 pairs.)

It's funny, 2.0 worked significantly better for me, even with some known bugs.
I hope everything can be fixed in the EA and this is funny money anyway.

yep, terrible terrible day.. probably because 2.2 is closing in profit too late instead of close of candle. The one at work was running 2.1 with 100 pip stop on all pairs.. bad bad idea. The +1 high/low did not change the 100 stop either and I left it running all day since it was so bad anyway.. It lost over $600.

2.2 results below

EJ +$8.26
EU +$19.00
GJ -$447.21
GU +$236.00
uj -$131.13

Total -$315.08

Pavatar,

Great work on the EA!

This would be my first post to the thread, but I have been following for a while. I certainly don't want to step on anyone's toes, but I do have a suggestion.

Instead of having the EA close orders at 1759:59, you may want to think about the delay it can take orders to reach the broker and be processed. I am not a coder by any means, and I don't know how difficult it would be to modify, but if you want your order's closed on Friday, I'd be sending those orders to my broker at 17:55!

Just a thought!

Sirken it is 17:59 GMT, which is 12:59pm EST well before the brokers close on Friday, which I think the earliest is 4pm EST

Hey llambert3 and all -

Fixed the close problem last night. Just a stupid mistake on my part - I've been in this 'fix one, break one' slump the last couple days - frustrating but these little slumps happen in coding, at least for me. I've got one other slight change to make and then I'll post the next version sometime later today - going out to take my frustrations out on a little golf ball; probably a lot of little golf balls given the state of my golf game and the amount of forest and ponds on this particular golf course!

I need some feed back from Damon once his computer is fixed about the SL issue and I need to post a summary of what I think the ea is doing and not doing, see what else we need per earlier posts, clean up any other errors folks have noticed and then rewrite my 'to do' list. I'd like to take the rest of the weekend to try and get a 'clean' version of the ea ready for Sunday night. In the week since I posted version 2.0 then been lots of rewrites and I need to carefully check it all out while trading is closed.

Have a wonderful weekend and I'll post a bit later today with the next version. Thanks for the ea feedback, testing and good ideas!
