Hi,

Would anyone tell me how to get the highest & lowest reading of an indicator over the past 30 days!

thanks,

what is the code for
buy area = daily open price + (20% * daily open)
sell area = daily open price - (20% * daily open)

Here we go,

#property copyright "Copyright © 2009, Arshed Qureshi. ArshadFX"
#property indicator_chart_window


extern int Percent = 20;

// --- Main Function call -----------------------------------------------------
int start()
{
double high = iHigh(Symbol(),PERIOD_D1,0);
double low = iLow(Symbol(),PERIOD_D1,0);
double Range =(high-low); if(Digits<4) Range=Range*100; else Range=Range*10000;
double GetPer = Percent*(Range/100);

// ----------------------------------------------------------------------------
Comment ("High : ",high,", Low : ",low,", Range : ",Range,"\n",Percent,"% : ",GetPer);
return(0);
}
// --- End of Main Function ---------------------------------------------------

Hello,

I'm currently trading with a martingale EA which will open max 4 levels of orders. I just think of a hedging strategy that may reduce the risk of using this EA. Below is a description of my strategy:

1. The hedging EA will monitor the drawdown of the opening orders. If the total floating losses is greater than a pre-determined amount, it will trigger the EA to open a hedged order in opposite to the opening orders.

2. The lot size of the hedged order is calculated based on a multiple (user can set the multiple) of the lot size of the last opening order (e.g. if the lot size of the last level order is 1.6 and the multiple is set at 2, then the hedged order will be open with lot size at 3.2.

3. When the hedged order returned to its opening level, the hedged order will be closed automatically.

4. When the overall basket (the opening orders + the hedged order) reaches a pre-determined net profit amount, all orders will be closed.

I wonder if some good programmer can code this hedging EA for me. I think it will be very useful for other martingale EA as well. Thanks a lot!

Best regards,

Wallace

whoa..
thanks guys..
how about buy stop and sell stop?
just change "BUY" over there?
just want 2 positions only for 1 pairs, not more than that..
sorry, still newbie..

Hi, i'm a new learner and interested to learn mql, can someone tell me how to code this into EA ?

Thanks guys =^_^=

It's easy.
When you start your indi, Bars=1000 (for example) and counted_bars=0. So limit=1000 and your indi calculates all 1000 bars. After this counted_bars=1000, and every new tick indi calculates only last (zero) bar. When next bar comes, limit=1 and indi recalculates two last bars.
b3[i] = Low[i]-10*Point; - it's just a line 10 points lower then bar's minimum.

If you want to use this indicator in an ea you can use the icustom() function to access it. you dont really need to understand any of the code of the indicator, just the data that it spits out. At least thats the easy way to do it.

Meaning to say, use the function icustom() in the EA to recall the indis ? how should the coding to be written in the EA ? can give me some guide ?

Many Thanks
