I'm trying to code a stop on my EA, but I can't figure out how it is using MACD_Histogram indicator - MQL4 and MetaTrader 4

Константин Скворцов 2009.02.10 10:30 #31

on a signal: fractal (indicator olyakish). only 1 position is opened, which is closed on the opposite fractal and the opposite position is immediately opened. Objective: to code a stop at the minimum or maximum value of the fractal at which the position was opened +\- 5 pips.

Any questions from newcomers Internal loop: PositionClose Something interesting, old thread

Aleksandr Pak 2009.02.10 10:35 #32

You should definitely check
- if the price at the time of opening the order has gone +/-5 pt from the fractal
- or catch the moment to open when the price is in the corridor +/-5 from the fractal
= put stops / sticks + then check the freezing levels

Hello Gentlemen Professionals!

Finally my brain has figured out how to install an EA, but,

I've installed Rabbit3 - run it, set autotrade permission. I've got Rabbit3 here, I've got a Buy or Sell order. Lot 0.01, Sell and Buy buttons are inactive, and when I change lot to 0.1, "Not enough money". What should I do? Is this EA capable of micro lot trading or not?

I decided to code position opening using MACD_Histogram indicator(found in base https://www.mql5.com/ru/code/8253), but I can't figure out how to code it correctly. I should add some fixes to indicator, it has no errors when compiling, but tester blames buffers. Please advise how and what to fix.

Can't anyone help me with a question...

you need to set the properties

see examples in the same MASD code

Take the Expert Advisor, e.g. MACD Sample, comes with MT4. Look at its code. It uses the MACD indicator but does not have any buffers. Doesn't it? Instead it accesses the indicator values through iMACD(....). It is the same in your case, you should not redo the indicator for trading, but take your Expert Advisor and modify it to work with your indicator. And to address to indicator values through iCustom (....) (Rules of use are in the help and tutorial). If you have more exact questions, please, ask.
