Alerts on Studies

[Lancer]

Wanted: EFS files for Alerts on Studies.

"New 7.2 Advanced Charting Enhancements:
Alerts on Studies -- Users will now be able to tie an alert pop-up or sound to a study through EFS, so you'll be alerted to buy and sell opportunities."

Do you have EFS files for Alerts on Studies? If so, please post files in File Sharing and post your link in this thread.

Examples of some basic alerts needed:

Moving average crossover (>= and <=)
Stochastic %K/%D crossover (>= and <=)
Bollinger Band penetrations
Study/Price Divergence

For various studies (%K, %D, RSI, CCI, etc.):
Study relative to scale value (>= and <=)

Etc.

Thanks to all who contribute.

Lancer, included in build 510 in your /formulas/505 folder are some alert samples. I believe one of them is a MA xover.

If you look at those, you can also look at some of the /formulas/builtin samples to combine them and make the formulas you list.

Let's have some fun

Here's the original AlertMA.efs formula that does an Alert with price goes above the MA.

    return v;
}

With minimal modification to the original formula, I took some code from /formulas/builtin/builtinMA.efs

Now we have an alert when a 10 bar MA crosses the 50 bar MA.

Matt, you're the EFS expert. For you, EFS is easy and fun. I'm just a trader that wants better tools. I don't know anything about writing EFS files. When first confronted with EFS in eSignal, I looked into learning about it, but I couldn't find complete documentation posted anywhere (all functions, operators, etc., proper syntax, format, etc., all the how-to's). I really just want to trade, and do a little tweaking to existing file settings. That's about it.

Those three alerts examples in Formulas>Alerts hint at the promise of Alerts on Studies, but they do little more than that. A basic alerts file-set is needed.

Thanks for the Moving Average Crossover formula. That's a good one to start this thread. I'll tweak the values and try it tomorrow.


In edit: I added the MA Crossover formula to a chart, and the result was #Formula Error#.
