Trade less. A lot less. Its that simple. The biggest problem that most traders make is taking profits too quickly. This leads to overtrading. Some market dunces have quaint sayings like " you never go broke taking a profit. " That is just bs. If you take profits too quickly, you will go nowhere in this business. Trading less is closely related to the one thing people need to do. Sit. And watch and wait. Wait some more and keep waiting. Being selective in one's trades is a way to reduce trading, have longer time frames, and keep losses small because the entry will by nature be good because of your selectivity. Good entries allow fairly tight stops with big price targets providing a good risk reward ratio. I am assuming that one has had some success trading and has a winning system or discretionary method. Look over your trades and see which ones have made you money and which ones have lost you money. The few best trades and trade ideas likely provided most if not all of the profits on your trading.
