Patience is easy to say and hard to do. The fix is to write your plan down before you buy, while you are calm. A written plan turns good intentions into steps you can actually follow when price is moving and emotions are loud.
A simple plan answers a few questions. What am I buying, and why. The total amount I am willing to commit. The exact price levels where I will add, from high to low. And the reason that would make me stop and walk away.
Keep it short enough to read in ten seconds. The whole point is that when a dip comes, you are not deciding under stress. You are just checking your own list and doing the next step it tells you.
Decide your budget, your buy levels, and your walk-away reason in advance, in writing. Then your job during a dip is to follow the list, not to feel your way through it.
Tip. Practice the plan in the accumulation simulator before risking real money. Following your own written levels through a fake dip builds the exact habit you need when it is real.
