Stop asking "Can I go long now," the facts have already given the answer:

Forecast bullish → students enter long positions → the market rises as expected → take profit and exit, all in one smooth flow.
You're hesitating at 81100 whether to chase, while others have already entered and taken profits;
You're debating at 81700 whether to exit, while others are already cashing out and relaxing.
The market isn't short of opportunities, what it lacks are people who follow the trend correctly and dare to execute.
