Hello, thanks for question, but I'm not sure if I understand question correctly. 

So, you are using this indicator, and also some other expert advisor "Big Trend V140", correct?

And this EA( Big Trend V140 ) cant read the indicators buffers? Am I correct?


Thanks

Ekaterina

Yes I use the indicator inside an expert.

I understand now the situation. So, to "connect"/use MT4 indicator into MT4 EA we need these things :

- indicator buffers

- know indicator "empty value"

- use iCustom function


This indicator has 4 buffers(buffer0,buffer1,buffer2,buffer3) as you can see in Data Window;

Indicator's indexes empty value = 0;  


The iCustom function is the most "human" function, because you manually need to re-write indicator's

inputs / parametres and define buy/sell signal conditions.

I have doubts that EA uses indicator's settings/parametres and EA defined correctly enter points. 

I have seen several similar EA's that can uses different indicators, but all these EA's are not so perfect,

you always need correct manually, indicator's inputs and trading buffer conditions. 


Something similar to this : If indicator's buffer 0 was "empty value" on previous bar, and on current bar buffer 0  != "empty value"

... then open a buy trade (just example);


So, finally, this indicator has buffers(please look picture) and it's empty value = 0; It means that from inicator's side

is done everything to have possibility interact with MT4 Robot. 


Please look the part of code in your Expert where iCustom is placed. May be there is something wrong, also check if your

EA uses correct indicator's name, all needable inputs are written in iCustom, and how trading(buy/sell) conditions are formed/defined in your EA.


Hope it was helpfull.


Thanks

I found a solution , I use the type float instead of double

Can you change in the data window the number of decimal for 6.

Thank you.
