There is no strategy as buy quick and sell quick. This is because no one know the right time to buy, otherwise no one would be buying when others are selling or selling when the market is buying. Trading is a business and is risky too. We can only make predictions and if it favors us then we are happy. Otherwise we cry in loss.
Risk is behind all the time as we take decisions, so as we cry after the loss; buying fast or selling fast isn't a good idea. We need to think of more options on how to deal with it into optimum tolerance to deal in. Don't rely seriously on predictions, just use it as your awareness in order to maintain your desired analysis.
