efs2 ALERT between 2 time periods

[commanderco]

Hi Alex
Is it possible to set up an alert between a stochastic in 2 different time periods?
For example
efs 2 stochastic %K =2 in 5 minute mode and
efs 2 stochastic %K =2 in 10 minute mode

The alert would trigger at minutes 00,10,20,30,40,50
when the two stochs diverge.
ie one goes up and the other goes down.
Many thanks

Yes it is possible. To do that you would use the getBarStateInterval() statement to check for the conditions only when a new 10 min bar is created.
Assume that we have two Stochastic studies based on different intervals (you need to declare the variables StochK1 and StochK2 as global variables and set them to null)

if(StochK1==null) StochK1 = stochK(14,1,1,inv(5));
if(StochK2==null) StochK2 = stochK(14,1,1,inv(10)); 

Then we can set up the conditions in the following way

if(getBarStateInterval("10")==BARSTATE_NEWBAR){//when a new 10 minute bar is created
        if(StochK1.getValue(-1)>StochK1.getValue(-2)&&//if 5min stoch of prior bar > 5min stoch of 2 bars ago AND
           StochK2.getValue(-1)<StochK2.getValue(-2)||//10min stoch or prior bar < 10min stoch of 2 bars ago OR
           StochK1.getValue(-1)<StochK1.getValue(-2)&&//conditions opposite to the above
           StochK2.getValue(-1)>StochK2.getValue(-2)){
               Alert.playSound("ding.wav");//play sound
        }
    } 

Notice that I am using xxx.getValue(-x) in the conditions since I am evaluating historical values that are not going to change in real time.
For the return statement instead you would return an array with getSeries(StochK1) and getSeries(StochK2) so as to maintain the syncronization of the plots.

Hi Alex, this is fantastic.
However I am still too new to efs and too pre occupied with trading to know what to do with it.
Is is possible to get the completed code?
Many thanks

Hi Ian,

get in touch... your email is bouncing. I did an efs for you in London.
