Having the signal is half the trade. The other half is HOW you take it — and that's where most traders give away the edge they held in their hands.

Chasing the candle. The signal says "enter in the zone." You enter 40 points higher because "it's running." Now your stop is huge and your R is trash. Enter in the zone, or don't enter.
Not respecting the stop. You move it "just this once." Once is every time. The stop is sacred.
Cutting the winner early / letting the loser run. The exact opposite of what works. Manage with rules, not emotion.
Break-even after the first objective — protect the capital.
Partial as the trade runs in your favor — lock something in.
Let the runner go toward the MindDraw — this is how you capture the fat pitch.
Enter well and manage with rules and the SAME system flips from losing to winning. Two traders take the identical signal — one nets +150, the other −30. The difference is entirely in these four decisions.
Enter in the zone, keep the stop sacred, take a partial to break-even, and let the runner breathe toward the MindDraw. Same signal, disciplined management — that's the other half of the trade.
