Open Second Order in oposite direction ONLY

New comment
 
How to code this in EA.
You see the code below:
Just to say that Buy signal does not mean close sell orders.
So if there is Buy Signal and no open trades then Open Buy.
Then if there is Sell Signal and Buy order is opened then Open Sell but do not close Buy order.
Buy orders and sell order are closed by DIFFERENT signals no with Buy and Sell Signals.
Then if there is Close Buy Signal then close Buy order but do not open another Sell order if there is no Sell Signal.
So there should be max 2 orders opened at time.
The same with Sell orders but reversed.
Can you help?
Jeff

Try this:
I haven't tested, but these changes should open 2nd order if opposite trade signal is found, and closes each buy or sell separately.

Thank you.What is [b] for?Are you sure that CalculateCurrentOrders will alow to open more then 1 order?
Please check it(compile it) .I can not do it alone.
 
Reload post. I was going to make changes in bold type, but the [code] does not allow this. so I removed all [b] insertions. You will need to add changes to EA and test it yourself. Presently, I do not have time to do this.
 
I am sorry to say but nothing works ok.It is impossible to compile.Too many errors.
 
Try this:
It now compiles OK. I optimized the EA for last month and these are the new settings. Testing with MetaQuotes History Data, these settings returned 21% profit for month of Aug'07. Moving Average EA should be optimized every 2-3 weeks max. Even more frequent is better.

Thank you Very much.Now it works fine.
Just when you test at strategy tester there is message in journal,ALSO when attach to trade on chart:
"2007.09.03 19:19:43 2007.09.03 19:05 Moving Average GBPUSD,M1: invalid integer number as parameter 1 for OrderSelect function"

Is there any problem???
 
Try this:
This change eliminates the parameter 1 error. I'm always amazed how a code change that you would think should have very little effect on EA profit, in fact does effect profit greatly. I re-optimized and here are new settings that produces just over 23% profit for aug'07.

Wackena thank you very,very much.
Jeff
 
Wackena there is one unespected problem,if you change parameters for close orders to be different from open orders like I want EA opens 3 orders?! insted of 2.
Why is that?

This EA uses same iMA() value to open and close orders. A Buy signal closes Sell open order and Sell signal closes open Buy order. Can you post an example. I not sure I know what you mean.
