funny story for all whose reading... last week a stock tanked $2 in what seemed like a heartbeat... my running down now ( the fastest) gave no alerts but the running down gave all....and I missed the trade. so, I went and created another alert window so that I have both... today, same scenario...only this time stock tanks and it shows up on running down now not the other. so, for all traders...make sure you have multiple alert windows created so this doesnt happen to you.
