I only need this for use in an EA...

I need to be able to get the value of the linear regression line for a period of 8, but I need to know the value for both the current bar, and a previous bar...

Aka.. I'd like to do something like...

if (LinReg(8)[0] < LinReg(8)[1])
{

}

Anyone got a linear regression indicator that can do something like this? :)

 

I downloaded and installed _linreg.mq4 and compiled it, restarted MQ4, and have tried calling it in my EA code and all it says is...

'_linreg' - function is not defined.

I also tried just linreg without the _, and it still says 'linreg' - function is not defined.

What's the proper way to get the value from an EA?

I got it from https://www.mql5.com/en/code/8139

 

You will be needing iCustom(). You can then index any bar you like.

Thanks for the help...

I added this line to my EA...

Print("iCustom(this is me): " + iCustom(NULL, 0, "_linreg", 0, 0));

And this is what I see in the journal... (when backtesting)

2010.07.24 16:39:01 2010.07.23 22:00 MyStrategy EURUSD,H1: iCustom(this is me): 2147483647.00000000
2010.07.24 16:39:01 2010.07.23 21:00 MyStrategy EURUSD,H1: iCustom(this is me): 2147483647.00000000
2010.07.24 16:39:01 2010.07.23 20:00 MyStrategy EURUSD,H1: iCustom(this is me): 2147483647.00000000

It's always the same value of 2147483647.00000000, as far back as I can scroll in the journal, for the whole backtest...

Anyone know why?

I got _linreg from https://www.mql5.com/en/code/8139 and it looks like a normal linear regression line when I add it to a chart...

Anyone know what's the matter with my code?

 

Misuse of iCustom()

try

Print("iCustom(this is me): " + iCustom(NULL, 0, "_linreg", 13, 0, 0));

 

Here is what my code looks like now...


int start()

{

Print("iCustom(this is me): " + iCustom(NULL, 0, "_linreg", 13, 0, 0));


And it still outputs this to the journal...

2010.07.24 17:36:47 2010.07.23 22:00 MyStrategy EURUSD,H1: iCustom(this is me): 2147483647.00000000

Any other ideas?

 

Nope.

Print("iCustom(this is me): " + iCustom(NULL, 0, "linreg", 13, 0, 0));
Print("iCustom(this is me): " + iCustom(NULL, 0, "linreg", 13, 0, 1));
Print("iCustom(this is me): " + iCustom(NULL, 0, "linreg", 13, 0, 2));
Print("iCustom(this is me): " + iCustom(NULL, 0, "linreg", 13, 0, 3));
Print("iCustom(this is me): " + iCustom(NULL, 0, "linreg", 13, 0, 4));

"linreg" vs "_linreg"
