I hope, it may be helpful for you.
Hi thanx for the reply .
I didn t use the proper mt4 function . Mathabs is the correct one .
Please find here below a working version of the indicator .
Can be improved of course but with fine tuning of the Interspread var ,alarm can be very helpful indeed !

Hello ,
I have been practising my trading for 2 years now .In order to improve my gains , i have been looking for an indicator that would alert me when there are "important" price variations . This could be helpful for nights important fluctuations .
The most appropiate indicator I could find is the Detrended Price Oscillator one .
Howether , there is no alarm at all !
I tried to fix it in order to set an alarm signal when DPO is superior to an given value .
Of course , since I am very bad at programming , it doesn t work ...
Looking for some help to either fix it or to find another suitable indicator .
I think this would be a basic but nether the less ,helful indicator
thanx
dawe
