Just want to make a note on PA. I don't expect anyone to respond during market hours.
If I watch a particular script every minute from 9.15AM, then I find I can make money using PA since i know the support and resistance, how the stock is moving, and what the spread is. Also, the profit is almost instantaneously made when I execute the order.
If I don't watch a particular script continuously, but simply trade it based on what I have seen in the last 2-3 minutes, I don't do as well. Here, it requires some time to make profit and you need to have the guts to hold on. Perhaps this needs practice...
