Long time lurker first time poster lol Is there a provider out there that can give me alerts on what instrument is moving at any given time? ie. ALERT: XXX.LSE has moved 2xATR in the last 30 minutes ALERT: GOOG.xxx has moved 1xATR in the last 5 minutes etc etc I think i recall seeing somthing a while ago but cant remember. Volatility = $ for most small traders so this would seem to be a pretty popular tool no? Thanks!
