I'm using radarscreen to analyze the time and sales of a list of stocks. The problem is that radar screen isn't working well. It misses prints, and therefore gives false indications or just misses out on the alert entirely. I'm only using 2 nested if statements, I think it should be faster. Either it can't run my script fast enough, or it just doesn't check for updates to the t&s at fast enought intervals. It's not a huge list, just 30 stocks for now, althought I would like to expand it. Does anyone know of a realtime scanner that doesn't miss prints, is reliable, and is extremely fast that might work for the situation I am describing..
