A doubt about how an alert on ema on a server works: EMA (and many other indicators) in reality is influenced by all data available of the timeseries being measured - so maybe while I am watching a chart I have downloaded 4000 datapoints, but that might change, maybe I will download more, which will (slightly, OK!) influence the EMA..........
My question: if on a trading platform (like eSignal or ProRealTime or similar) I set an alert on an EMA - then how many periods will this alert "look at"? The problem I have with this is that I do not want to set up a tech alert, have it triggered, and then when I go to the chart i see it was triggered because on the server they were observing a different number of datapoints to what I was looking at in the chart.
Does that make sense and does anybody have comments? Is there a "standard practice" for how server side alerts on EMA (and others) are set up?
