Hi All,

I`m quit new here, and i reading trough the manuals
I would like to build an EA.
I copied a EA from someone else to make some changes that it fits my one criteria.

If I try to backtest this system it does not take any positions.
I hope someone can advise how I can make amendments in the system to generate signals to enter a position.

Here is my idea:
I want to trade on a 20 Day high or 20 day low
As soon as I receive a signal te enter I want to trade 1position( 1.0)
I want to close the position if it crosses the 10 day high/low in the other direction of the trade itself.

I only want to open 1 position each time, so as soon as I have a position I should not get an other signal to double the position.
See attached the EA that i would like to amend to the above criteria

Can someone help?
Thanks in advance

System 'Donchain counter-channel' was described in the Currency Trader
Magazine, Octobre 2005, p.32.

Rules:
1. Go long next day at market if the 20-day
lower Donchian channel line turns up.
2. Go short next day at market if the upper 20-day
Donchian channel line turns down.
3. Exit long with a stop at the lower 20-day Donchian
channel line.
4. Exit short with a stop at the upper 20-day
Donchian channel line.

Strategy uses a custom indicator "Donchain Channels - Generalized version.mq4", which must be put in the indicators
subfolder.

Version Date Comment
1.0 9 Oct 2005 First version based on the article from the Currency Trader magazine.

  1. No slaves here, learn to code or pay someone. Change the Donchian Channels/stop logic to your idea.


  2. EAs must adjust to 5 digit brokers, TP, SL, AND slippage. On ECN brokers you must open and THEN set stops
    //++++ These are adjusted for 5 digit brokers.
    int     pips2points;    // slippage  3 pips    3=points    30=points
    double  pips2dbl;       // Stoploss 15 pips    0.0015      0.00150
    int     Digits.pips;    // DoubleToStr(dbl/pips2dbl, Digits.pips)
    int     init(){
        if (Digits == 5 || Digits == 3){    // Adjust for five (5) digit brokers.
                    pips2dbl    = Point*10; pips2points = 10;   Digits.pips = 1;
        } else {    pips2dbl    = Point;    pips2points =  1;   Digits.pips = 0; }
        // OrderSend(... Slippage.Pips * pips2points, Bid - StopLossPips * pips2dbl

Help you with what? You haven't stated a problem, you stated a want.
You have only four choices:
  1. Search for it,
  2. Beg at
  3. learn to code it. If you don't learn MQL4/5, there is no common language for us to communicate. If we tell you what you need, you can't code it. If we give you the code, you don't know how to integrate it into yours.
  4. or pay (Freelance) someone to code it.
We're not going to code it for you (although it could happen if you are lucky or the problem is interesting.) We are willing to help you when you post your attempt (using CODE button) and state the nature of your problem.
          No free help
          urgent help.
