I have made an EA which call an indicator. when I test it on strategy tester , it is ok and in the journal we can see all the information about when and which price the order open and close. If I add the "Print();" in EA, after test, in

I ask this question just because I have test it; and sometime the indicator was shown on chart, but most time, not. So I don't know why

according to my acknowledge, when we send an order on MT4 with its stop loss by ordersend(), the MT4 operator can see the stop loss, and if we set stop loss by EA, nobody can see it. so why not set 0 as stop loss in Ordersend() and set real stop loss

I have made an EA with a function to move " stop loss ", I set two parameters for this function"extern int Move_Stop_Small=5,Move_Stop_Big=10;", when I test it many times and modified these two parameters many times, once I set

the bars like below picture shows; most time I want to get bar A rather than bar B;but use iLowest(), it is easily to get bar B; so how get bar A

About below Indicator, I have some questions as below: 1. when " #property indicator_chart_window" is available, we get the result is: when "#property indicator_separate_window" is available, we get the result is: the first

Just now I have import historical data into MT4, and the data is from 2001.1.2 to 2013.11.29; and now my terminal shows like below, that is because of lack data from 2013. 12.02 to now; so my question is how to add these data into MT4

The below codes are in Indicator, and I want to know the difference when I change a little About this Indicator, I don't want to draw any indicator in Terminal, I just want to select some points in Indicator and call this indicator in EA by

I have made an EA and test it, it is ok, the result profit is 5000; to optimize the EA, I copy it on an blank EA, named "test_0", then I changed many variables to test, and at last i find it become worse when I change variables. Now I copy

about below codes, it is very different when the red code " if(Pro<10000*Point) " is activated or not when I test it on the history data; In the fact the history data is very simple, about consecutive 5 days, and Pro never exceeds

When we want to get value from an Indicator, we always should use iCustom() to get, and the value must be stored in a double array which also should be defined as indicator buffer ; so when we can only get double value from Indicator by iCustom()

I want to write an indicator to connect all the peak which meet my requirement (a little like ZigZag, but different for defining the peak); I write the codes as below, but the codes never work well, and I don;t know where something wrong exist. the

1. for the same EA, data of the same time section, for example, from 2013.5.1 to now; I test the EA on time frame H1 and M5 separately, I find 2020 bars have been tested in H1 and 5857 bars in M5; but I think tested bars in M5 should be 12 times of

My EA code is as below: int i_0= 0 ,i_1= 0 ,i_2= 0 ; double x[ 50 ],y[ 50 ],z[ 50 ]; int init()   {     ArrayInitialize (x, 0.0 ); ArrayInitialize (y, 0.0 ); ArrayInitialize (z, 0.0 );    return ( 0 );

I mean some time I create an object, a text, and set it on a bar's open time and high price; some time later, I want to view this bar's information, open price , open time and so on,so shall I get this information when I just know an object 'xyz' was

the code for an Indicator #property indicator_chart_window #property indicator_buffers 1 #property indicator_color1 Yellow // High Points Array Line extern int Seek_Period= 30 ; double Bar_High[]; int init()   {

The code is very simple, but I can't understand why MT4's expert complain that "array to be set is of incompatible type" My codes are as below: #property indicator_separate_window int counted= 0 ; #property indicator_buffers 2 #property

each time I create a new EA or Indicator by "Expert Advisor Wizard", and I find we can select "Generate from template", in which I find just several temples; so shall I add some new temple which made by myself? I have tried copy

for example, now I have made an Indicator "x_y" and an function "x_y", and they make all most the same work---draw two lines, one connect all the low points, the other connect all the high points, and of course some of the points

I mean I use OrderModify() to change stop loss line ticket by ticket, each time an arrow will be produced(as below picture); this must give computer more burden and also I don;t want to see so much arrows. So how or what I set to get no arrows when
