Help, please with return on LR ext.

[Diane P]

Hello,
I'm trying to add an extension to a linear regression indicator, but I can't get a proper return. Can you please help? Thank you.

There are a couple of errors in the script.
The first one is that there is an extra closing curly bracket in line 24.
The second is that while you do correctly transfer the value of LR to LR_1 at every new bar you then omitted to assign a value to LR. To correct this insert a line after the following section of code
if(getBarState()==BARSTATE_NEWBAR){
LR_1=LR;
}
and in it add the following
LR = wt;
This will assign the value of wt to the variable LR.
Then insert another line after that and in it add
if(LR==null||LR_1==null) return;
This is a null check on the LR and LR_1 values before you use them as parameters of the addLineTool() function else you will get an invalid parameter error message.
Once you implement these changes the efs will work correctly
