Live to trade another day.....From my colleague Joe Easton: Having trading discipline is essential to becoming a successful trader. Patience and discipline are the two most important skills aside from the ability to read a chart. Having “mental capital” helps keeps discipline. Things like proper sleep, nutrition and exercise can help maintain mental capital. Also, taking partial profits and minimizing risk will help keep your mind sharp and a higher chance to remain disciplined. Make less trades and stick to the rules including stop and start times. When you say this is the last trade or after this trade I’m flat, you must keep your plan. There is always tomorrow, make sure you stay in the position to trade the next day.
