Try this:

Frac(Minute()/5)=0

Hi Nishant

I've prepared an indicator and exploration version of my "Multi-Frame ID Stoch EMA" indicator that I think will signal on tick, 1 or 5 minute charts each time the 5-minute Stoch(14,3) crosses below 20. This is achieved by running the indicator/expert formula in "dynamic" mode so that each new data point is regarded as the final bar of the current 5-minute period/frame.

It should be possible to configure the expert so that only one cross below 20, or each of more than one, will trigger a signal. Dynamic mode allows you to monitor the indicator state or value of the currently evolving 5-minute timeframe. Static mode will only signal a cross below 20 once the 5-minute frame/period has been completed and the first tick of a new frame is available.

Proprietary elements of my formulas are not shown here but I will get all code to you once I have your email address. With cooperation on both sides I'm sure we can make this thing work.

Currently the Expert Advisor works chart by chart, so I think John's suggestion would be on a per chart basis, hence your problem should not be an issue in the case of A and B firing off within 2 minutes of each other. I believe John was suggesting each chart will fire off the first trigger then stop until the next 5-min bar. But if you had 30 charts open and they all triggers within 30 seconds of each other, you would get 30 pop-ups within 30 seconds, then nothing on any of the charts for 4 min 30 sec.

Detaching alerts from charts is something we want to do eventually. It would be an "Alert Manager" of sorts. This would be a natural extension of adding an automatically generated trade ticket (based on alerts) for brokerages as well.
