My Rule for stock trade

1. Buy low, sell high.2. When market on the top area (never know when and where the top will be), short stocks; when marke in the bottom area, long stocks.3. Once he(stock) on the way of up, no matter in the middle or the top, I don't want to chase, Or I will chase it only if I amd 100% sure that I can catch it it the middle of the way ( I can make profit).4. Never do brainless follows5. Cut loss or lot depend on " will I buy the stock at current price" instead of what percentage of loss.6. Do swing trade instead of long term investment when direction is unclear ( less than 2 weeks?) or out of market.
