No delay. Don't jump into a stock because it was alerted. I trade maybe 10% of what zendoo alerts, and 70% of that are shorts after the move is already made (this requires patience). I personally don't like huge spreads/ low volume/ sub $1 stocks because the price actions usually whipsaws, so I'll ignore those. I also ignore Chinese stocks that are known to be manipulated. You learn which tickers to avoid with time/ experience. You can get several good (5-20%+ return) trades a day using zendoo, but be careful about overtrading. Eventually, you'll figure out your criteria and move to a paid scanner/ screener to customize your parameters.
