I've been at this 4 weeks and still no clue,
it's roughly this,
if OP_BUY EUR/USD minus OP_SELL USD/CHF equals minus 100 ignore other trades and
close both orders together

I've tried everything loops within loops etc and nothing works

I'm working on money management and am pulling my hair out any help or clue very welcomed.

with thanks

I presume this is a hedge and you are referring to the accrued profit of each, above. You need find what these are using OrderSelect and OrderProfit() functions, then:

if (MathMax(EU_Profit,UC_Profit) + MathMin(EU_Profit,UC_Profit) < -100)
{
OrderClose(EU_Ticket...
OrderClose(EC_Ticket...
}

Hmmm... seems too simple to spend 4 weeks on so you are probably trying to do something else.....

I'm not a programmer just put bits and pieces and hope they work using some logic of course!

Thankyou very much!

Trivial question: I'm writing a new Personal Indicator for the first time. I can't view my logs that I make with the command Print("...") in the start{} method. Where I can view them on MetaTrader 4?

After looking at omelettes answer it's not what I need but certainly thankyou!

The problem:

Using one symbol for simplicity lets choose EUR/USD

If I have multiple BUY && SELL positions

I need to choose only one BUY position and only one SELL position

That together equal a variable of lets say of exactly -100

Every other order is untouched

Which BUY or SELL is irrelevant

The logic behind this is to keep BUY && SELL ratios correct for money management, a kind of stoploss that uses OrderClose() for both BUY && SELL

any help warmly appreciated

and thankyou

I have uploaded my feeble attempts to program relating to my last post, theres are many mistakes of course, it doesn't work!

Thankyou

I had a moment of spare time, and made an attempt to capture your intention as I understood it.

Thankyou ralph.ronnquist

these functions are exactly what I need and would be of use to others after a same function

I was caught up otherwise would have thanked you earlier especially because it took effort

Is there a simple way to change the function to work in strategy tester? I know the results of working with just one currency in the tester is next to useless except it mimics very roughly what I need in order to get the math right, any help is appreciated and I never would have worked the code out in short order so once again thankyou!

I'm having a little bit of trouble with this one.

I have the DT_ZZ.mq4 indicator and from what I see it's very promising. I do know that this indicator redraws and here's how I see it working.

If an arrow and section are equal, then wait for the bar to close, then buy/sell accordingly.

Anybody think they can help with that? (Code is posted below)

ralph.ronnquist

has provided me generously a great function that many may benefit from that require it's use.

My problem is because I'm so lousy currently at programming I can't seem to alter it enough 4 strategy tester.

For testing purposes only one currency is satisfactory just to work out the math of trades under different circumstances with different currencies.

Is it possible to change ralph's work to suit this need.

Thankyou
