I'm trying to write an ea but am having trouble. Hopefully someone can help. In the below section of the code, I want the Trailing Stop to be 3/4 (75%) of the ATR (20) indicator on the 1 Hour Time Frame:

Inserted Code
param.2.name=Trailing Stop (indicator)
param.2.id=TrailingStop
param.2.type=function
param.2.scope=verbatim
param.2.value=iATR(NULL, NULL,20,1)
param.2.hidden=0
param.2.category=
param.2.accvalue.list=

Next, I want the Stop Loss to be Current Price - ATR (20) on the 1 Hour Time Frame:

Inserted Code
param.3.name=Stoploss (indicator)
param.3.id=BuyStoploss
param.3.type=function
param.3.scope=verbatim
param.3.value=iATR(NULL, NULL,21,1)
param.3.hidden=0
param.3.category=
param.3.accvalue.list=

I know it's probably simple, but I'm not that great with coding. Any help would be greatly appreciated!

Thanks in advance!

For the current bar:
PHP Code
TS=iATR(NULL,PERIOD_H1,20,iBarShift(NULL, PERIOD_H1, Time[0]))*0.75;
SL=iATR(NULL,PERIOD_H1,20,iBarShift(NULL, PERIOD_H1, Time[0]));
You will have to add/subtract the values to/from the current price, of-course.

This is the main part I'm having trouble with. Any suggestions on how to apply this to the current price?

Also, how do I get it for the ATR (20) of the previous bar?

Thanks again in advance!

For the current H1 bar:
PHP Code
double ATR_H1_0=iATR(NULL,PERIOD_H1,20,0);
For the previous H1 bar:
PHP Code
double ATR_H1_1=iATR(NULL,PERIOD_H1,20,1);
