Often, I make use of the UTRADE TechAnalyzer tool to help me shortlist stocks. This can be found at Trading Tools -> TechAnalyzer -> MyStrategies. For instance, you can select RSI oversold as one of your criteria. The short listed list will be based on the last trading day price. To be safe, probably by 6pm can try to screen.
There you go! Quick and easy shortlisting.
From there on, I will see those that I am more familiar with, and look at their charts.
Then, I will decide from there.
Hope this tip helps!
