Staying disciplined after a big win

Losses get most of the attention, but big wins cause their own problems. It's common to feel invincible, raise position size, loosen the rules and give the gain back within days.

Has that happened to you? Tell us:

• what the win was, in R or as a percentage
• what you did differently in the trades that followed
• what rule, if any, you now follow after an unusually good day or week

Some traders keep size fixed for a set period after a large win; others simply stop for the day. Which works for you?
