One more question and I stop burdening you for today, I promise.
How to code the following: The standard deviation of the change in price over prior 20 days<0.8
Would the following code be correct?
stdev(sub(c,ref(c,-1)),20)<0.8
Thanks so much for your insights.

Hi meridien, You don't really need to use the Sub() function, as you can just write: which also happens to be the same as the one period rate of change: One of the best ways to learn how to program your own MS indicators, experts, explorations and system tests is to have several thorough reads through the MS Users Manual. Once this is complete, download the free Equis formula primer from the files section of the forum and work through those exercises. You can always look at the codes built-in to MS to see many other examples of code in action to give you some hints/ideas (some are password protected, but the majority are open for reading/editing). wabbit [:D]
