Help with array

Also, The reason i have done it this way, is so that i can smooth it by making a average. xlength is set to 1 at the moment, but i would change this to a higher amount.

When i want to know the time difference in seconds i do this

getValue("rawtime", 0) - getValue("rawtime", -1)

You may find it easier to use the new EFS2 syntax to create your study taking advantage of the efsInternal() function. This function will allow you to create a custom series that you can then feed as a source to the EFS2 builtin study.
In your script create a separate function called for example calcTimeDiff(). In that function then perform the following calculation directly in the return statement ie

return rawtime(0)-rawtime(-1);

Then in main() you can call that function with an efsInternal() call. Once you have done that you have essentially created a custom series which you can now use as a source for the builtin study

var vTimeDiff = efsInternal("calcTimeDiff");
var vAvgTimeDiff = sma(3,vTimeDiff);

At this point return vTimeDiff and vAvgTimeDiff and you have completed your script. In function TimeDiff() you may want to add a condition like for example if(getDay(0)!=getDay(-1)) return; which will prevent a spike on a change of day
For more information and examples on how to use efsInternal() see this thread
Note that EFS2 requires eSignal version 7.9 or later
