I'm trying to create an EA based on 1 custom indicator; How do I use it? - MQL4 and MetaTrader 4

Do a search for money management and martingale then take a look at the code in the EA's you find. That should give you a good start in the right direction.

xdealer:
Hi all,

this is my first post

Is there a way to detect open/close/modify trade events in mt4? There aren't any event callbacks are there?

I want to detect everything about a trade (by EA or manually) ASAP, what is the best way to do it?

I know I can parse the logs, but is there a more efficient way?

Thanks

It seems that I have to cycle though all orders and do the housekeeping, there is not even callbacks.

If this is ture then what is the best way to do to monitor all orders from different chart windows? Can an EA run w/o being attached to a window?

changing lot size

I've tried to edit this line:

err=OrderSend(Symbol(),OP_BUYLIMIT,0.1,NormalizeDouble(op,Digits),3,sl,tp,

from 0.1 lots to accountbalance/30000 (i.e. 0.01 for every $300) but nothing seems to work?

EA based on custom indicator

Hey guys I am new here. I don't have any programing experience so I would like to ask you for help.

I would like to create and EA based on 1 custom indicator but I simply can't do it. I was trying for over a week now and no luck.

My first problem is putting the indicator code in the EA ( I tried iCustom and some kind of alternative when you copy just a part of the indicator's code in the EA).

And after I somehow managed to input the code in the EA using iCustom function I don't have any idea how to make it to work

The indicator basically shows you when the crossover occurs and sends you alerts and arrows ( blue and red) depending of the buy / sell orders.

This is the indicator code:

#property indicator_chart_window

#property indicator_buffers 2

#property indicator_color1 DodgerBlue

#property indicator_width1 3

#property indicator_color2 Magenta

#property indicator_width2 3

What I would like to achieve is to make an EA that will do this:

Let's say crossover occurs and indicator show blue arrow ( BUY SIGNAL) ,I want EA to buy. They the indicator shows red arrow and I want EA to close the previous order (BUY) and make an immediate SELL order. Kinda like SAR type of thing.

Please help me on this one. I would be very grateful on any advice you can give me. Thanks

Lots traded per bar

Hi all,

Can someone give me an advice how to get actual number of lots traded per tick or per bar? I was searching throu MQ4 docs but trade volume has been defined as a tick count. Since one tick seems to be an actual trade, I am curious how I can get number of lots per each trade or total per each bar. MarketInfo does not have anything about traded lots, only Bid/Ask. Looks like MT4 does not provide this information directly. Is there any indirect way?

Thanks

Can I do Buffer=Close/Close?

Does anyone know how to make Percent decrease or Percent increase indicator?

I did that

for(int i = limit-i ; i>0 ; i--)

{

Buffer=Close/Close

}

But That was not working

So I changed above part / to - like that

Buffer=Close-Close

this Indicator was working

And I tried to

Comment（Close[0]/Close[1]）

This value was commented correctly.

So I can't understand why Buffer=Close/Close is not work.

Does any one answer my question?

and thanks for reading all.

Try this:

#property indicator_buffers 1

#property indicator_color1 Green

#property indicator_width1 2

int init()

{

SetIndexBuffer(0,buff); SetIndexStyle(0, DRAW_HISTOGRAM);

}

{

{

}

Entry Point.

With my EA that I have. I am trying to program it to take a position at the next time frame. If the indicators are true and it sends it to take a position then I want it to wait till the next frame. I.E with a 15 min. Chart at 10:35 the program is true for a "buy" position I want it to wait till 10:45 to enter. 3
