EMA Bollinger pierce alert assistance

[dr1990]

Hi, I'm new to the forum and my efs coding experience is limited to small custom adjustments to studies available in the eSignal efs library.

I would like a study that fires an alert with an EMA Bollinger pierce. I've attached the Bollinger Pierce alert available in eSignal and a BollingerEMA study I got from the efs library. I'm thinking the (BollingerStudy.UPPER) references in the function main of the Bollinger Pierce alert needs to be replaced by something from the BollingerEMA study but I don't know what, or if this is even the right approach. Perhaps what I'm looking for already exists but I haven't found it. Any advice appreciated. Thanks.

In case it helps I believe eSignal ver 11.5 allows for this in:
right click on chart, select "Insert Study", then open the "Built-In Studies" tab, then insert the "Bollinger Bands" study. Just edit the study. You set the alerts in the "Alerts" tab.

Yes it's easier now to apply alerts to the built-in studies but BollingerEMA isn't one. Still convinced this must be easy to do somehow but I'm getting nowhere. Thanks for posting.

Then assuming you are interested in an alert when price crosses the BB basis line, try the attached efs (I didn't test it, I'll leave that to you);

Hi Waynecd, the basis is just a moving average which is available built-in, it's the standard deviation bands that I'm interested in. But it looks like I just need to change the references to vUpper and vLower, is that correct? I'll experiment. Thanks a lot for taking the time to do this. Cheers

Yes!! Works with the bands too. Thanks Waynecd, that's exactly what I need. Cheers

Glad it worked.
