Getting previous histogram information
Use this: https://docs.mql4.com/predefined/variables/volume with the bar number you are interested in.
But i am using a custom Volume that has an ema displayed in a separate window, so i have to use icustome to use it in my EA . is there another way to do this?? using regular Volume??

Ah OK, yes use iCustom, are you passing all 3 Externs in the iCustom call ?
But i am using a custom Volume that has an ema displayed in a separate window, so i have to use icustome to use it in my EA . is there another way to do this?? using regular Volume??
RaptorUK:

Ah OK, yes use iCustom, are you passing all 3 Externs in the iCustom call ?
Yes, but it doesnt seem to work, or get the previous histogram ema cross information
prodi:
Yes, but it doesnt seem to work, or get the previous histogram ema cross information
Can you show your EA code or at least your iCustom calls ?
Yes, but it doesnt seem to work, or get the previous histogram ema cross information
- Indicator code:
//| Volume with Custom Moving Average.mq4 | double VolBuffer1[]; // value down double VolBuffer2[]; // value up double VolBuffer3[]; // moving averag extern int MA_Period=13; extern int MA_Shift=0; extern int MA_Mode=0;
What is the Exact file name of the indicator without the .mq4 extension?
EA code:#define CMA_NAME "Custom Moving Average" #define CMA_DOWN 0 #define CMA_UP 1 #define CMA_AVE 2 int MA_Period=13; int MA_Shift=0; int MA_Mode=0; double value = iCustom(NULL,0, CMA_NAME, MA_Period, MA_Shift, MA_Mode, CMA_AVE, 0);
- bear with me as i am not a coderlearn to code or pay someone. We're not going to code it FOR you. We are willing to HELP you.
Here is the icustom call
double GreenArrow=iCustom(NULL, 0, "MA Volumes",VMAPeriod,0,VMAMode,0,0); double RedArrow=iCustom(NULL, 0, "MA Volumes",VMAPeriod,0,VMAMode,1,0); double VMA=iCustom(NULL, 0, "MA Volumes",VMAPeriod,0,VMAMode,2,0);
And parameters
extern int VMAPeriod = 32; extern int VMAMode = 1;
Yes i have paid quite well for crappy coding unfortunately i have no choice but to get help

Can any one help? How do i get the previous volume histogram information on a current bar.
I want my EA to enter if all the rules are true on the current bar + a histogram cross above ema of the last previous candle
I tried this;
but it doesnt work.
bear with me as i am not a coder
