Return Upper/Lower for Obj_stddevchannel or Obj_regression?

Anyone know how to return the Upper/Lower for OBJ_STDDEVCHANNEL or OBJ_REGRESSION?

ObjectGetValueByShift() returns middle line. How to I get the outer lines?

I haven't worked with mql for a long time so it could be that there is a simple solution. I have not tried to solve this problem before but there should be a good way to do it, surprisingly enough I did not find anything useful in the doc and without an mt environment I can not try it out myself. Anyways below are 3 ways how I would tackle the problem.

1. Get the time and use https://docs.mql4.com/objects/objectgetvaluebytime. This function takes in an identifier for the line index which might give you what you want.

2. The deviation value is the same everywhere at the line. If you can calculate the std value for yourself you only need the getvaluebyshift and add or subtract it. Or same problem, you can also always get the equation for the line a*x+b whereas a is easily computable by taking 2 points and you still need to figure out the value for b.

3. It might be worth to take a look at the datatype object of the regression or stdchannel. You can initialize objects by using ObjectCreate() but you also can create the object by calling the .create method on the desired subclass of the CChartObject. There might be additional functions which already do what you desire.

No1 Works thanks!

ObjectCreate("xx",OBJ_REGRESSION,0, Time[finalBar],0,Time[initialBar],0);
Comment(ObjectGetValueByTime(0,"xx",Time[0],0)+" "+ObjectGetValueByTime(0,"xx",Time[0],1)+" "+ObjectGetValueByTime(0,"xx",Time[0],2));
