Trade-Ideas alert lags/alerts not appearing, alternatives?

[antares66]

You could programm something with TC2000s Easyscan, but you get only a refresh rate of 1 minute. In the worst case the train has left the station since one minute ;-)
For me it is sufficent

Has anyone tried this with say IQFeed and their API? Wondering about potential lag time?

i was reviewing some data from the 20th of november (big gap down spy day) and realized pulling history for my alerts on TI showed me stock alerts it had not shown me live - twice as many tickers alerts. a little more digging and I realized the timestamps on the alerts started right after the first minute after the open, but the prices being alerted had to have occurred much earlier, anywhere from 930:15 to 930:50 depending on the ticker. so the short version appears to be they couldn't process scans with the market volume early that day, and some alerts were not sent at all (and others late, which were not flagged as so and I did enter tickers into strategies based on late alerts).

I do have independent time-stamp on this as well as I pulled up charts/strategies based on the alerts given.

Once in a whlie a ticker pops up in history with TI which did not alert live, but this was unusual in the quantity and the lag involved.

are high volume open days like this a problem with all scanners? I haven't used equityfeed in years and don't even recall if I can scan for what I want to do on it, but I am open to any suggestions which might offer a reliable alternative.

%%Yes;
focus on a few, like SPY...…………………………………………………………………..

I used trade ideas few months back and i dont trust their alerts in alert windows. i didnt get good alerts when some stocks should have appeared in the scanner for obvious reasons, filters etc. I really have doubts on this over priced scanner. You dont need a Premium subscription for backtesting as the short cut is to choose History and do backtest but you cant see any equity curve etc for analysis.
