If you increase your trading just before the awful periods, you will lose money twice as fast as you made it. Knowing how to increase trading in a growing account is perhaps the most difficult problem for successful traders. Be cautious in adding to your trading. The best times to add are after losses or equity drawdowns. Don't become too depressed during drawdowns.
Trading is a lot like golf.
All golfers, regardless of their ability, have cycles of good play and poor play. When a golfer is playing well, he assumes he has found some secret in his swing and will never play poorly again. When he is hitting it sideways, he despairs he will never coming out of his slump. Trading is much the same. When you are making money, you are thinking about how wonderful trading is and how to expand your trading to achieve immense wealth.
