Entered for a short term trade

Volume was good and had to days of break out. I entered at 18.60

Been kinda stale since then. But having patience. I should have used the gap and go strategy this morning and bought at the first green bar on the 5 minute after the first red bar.

Stop loss at 18.30

Let me know your thoughts people.

My questions: When should you enter on the intraday? And what should the time horizon be for a play like this. Targeting only a 5% return.

Blessings!
