The calling names inside iCustom are most probably the culprit. What do you know about iCustom?

honest_knave 2014.04.24 16:54 #2

You missed out several of the parameters required for iStdDev - https://docs.mql4.com/indicators/istddev

Yours: (4 parameters)

iStdDev(Symbol(),0,Magic_Period,i)

Correct Example: (7 parameters)

iStdDev(NULL,0,10,0,MODE_EMA,PRICE_CLOSE,0)

Dear Knave,

Now there is no Error message, but the indicator not working, my BUY/SELL condition is Standerd Deviation Value Must be rising .

when other parameters are equal (Present bar SteDev Value > Previous bar SteDev value)

Please Help

I propose a new CustomIndicatorNotCalling Properly Any rookie question, so

honest_knave 2014.04.25 02:42 #5

Try changing the final parameter from 0 to i (and 1 to i+1):

iStdDev(Symbol(),0,Magic_Period,0,MODE_EMA,PRICE_CLOSE,0)>iStdDev(Symbol(),0,Magic_Period,0,MODE_EMA,PRICE_CLOSE,1))

iStdDev(Symbol(),0,Magic_Period,0,MODE_EMA,PRICE_CLOSE,i)>iStdDev(Symbol(),0,Magic_Period,0,MODE_EMA,PRICE_CLOSE,i+1))

ffoorr 2014.04.25 08:19 #6

 OnCalculate()

don't match with

IndicatorCounted();

try start() instead

U R Really Honest, thanks, it worked

honest_knave 2014.04.25 08:57 #8

IndicatorCounted() remains available either way, as does Bars().

You're welcome. Glad to help.
