Your trading plan must account for every possible eventuality the market CAN and WILL throw at you. Some of those include: when the triggers are strong, at what point will you enter your trend trades, and with what entry method? Will you get in at the best spot with a limit order, market order, a market flow signal, or use a stop entry order? Which different order types will you use with different market conditions? What are the conditions in which you will alter your entry logic? If the triggers are strong and there is a prior divergence, where will you enter and why? If there is a potential trouble spot, where will you enter and exit, how and why? If there is a parabolic trend, how, when, and where will you enter your trade and why? Every detail of your trading plan must be clearly thought-out, so you do not trade emotionally. Indicator-based entries and indicator-based exits help to remove the emotional component of trading.
