what's wrong with iCustom ?
I tried also with this one and the problem remain exactly the same, then, one more times: what's wrong with iCustom ?

Viffer:
I think your parameter count is incorrect. there are two inputs, gamma and CountBars missing.
Try this ...
Hope that helps.

Thanx but i tried already, same problem... it's driving me nutz
Not sure then, but with the correct paramenter count, it is returning the correct value
int start() { //---- Alert(iCustom(Symbol(),NULL,"Laguerre",0.7,950,0,0)); //---- return(0); }
Perhaps it's something to do with the for loop and i... not sure....
Try evaluating and printing the results outside the loop to make sure it makes sense.

What i really need is the value from H1 !
Again, still works fine...
int start() { //---- Alert(iCustom(Symbol(),NULL,"Laguerre",0.7,950,0,0)); Alert(iCustom(Symbol(),60,"Laguerre",0.7,950,0,0)); //---- return(0); }
Out of interest, have you tried breaking it down and using print to see what values are being returned?

i'm probably the worst coder on the board... i don't know how to do it. and your code seems return wrong values when i try it.
but maybe if you try my indicator on your MT4 you will find out the problem ? you need only Laguerre.mq4:
Many Thanx for the help

Just looking again at your OP, the first use of icustom is correct but the bit in Red for H1 has the wrong parameter count. If that's the only problem with your code then it's the parameter count that is the issue

Same problem with this one:

Just to be sure... the script I provided, did you change the parameters in icustom to match the input parameters for the indicator? I notice that the parameters in the version of laguerre are different from the one I just down loaded from codebase.
So does this still give the wrong result?
int start() { //---- Alert(iCustom(Symbol(),NULL,"Laguerre",0.66,9500,0,0)); Alert(iCustom(Symbol(),60,"Laguerre",0.66,9500,0,0)); //---- return(0); }

Hello,
I'm trying to code a very simple indicator using iCustom and Laguerre.mq4
when Laguerre cross the 0.75 level head down it gives a sell signal and when it cross the 0.15 level head up it gives a buy signal, it works but, of course it's not very useful like that and i have to add something else to make it more useful. this is where i fail:
i'm trying to check where is laguerre on H1 adding "&& (iCustom(NULL,60,"Laguerre",0,i) > 0.75)" and "&& (iCustom(NULL,60,"Laguerre",0,i) < 0.15)" in the conditions but it doesn't work and i can't figure out why, it gives random signal even if laguerre is not above 0.75 or below 0.15.
Your Help would be very welcome !
Thanx
here is the code (it's based on EMA cross indicator i found on the web) what do not work is written in RED:
