Opening a replay and clicking play until something happens is a way to spend an afternoon, not a way to train. Three decisions before the first bar make the difference.
Decide what this session is for
One focus per session. Entry timing, or stop placement, or sitting through drawdown — not all three. A session with one question produces an answer you can act on next time.
Write the focus down before you start. Deciding afterwards what a session was about is how every session becomes a success.
Set the constraints before the first bar
Instrument, timeframe, window, position size, maximum number of trades. Fixing these in advance means the session tests your rules rather than your mood, and it makes two sessions comparable.
A trade cap matters more than it sounds. Without one, a bad start turns into forty trades of revenge, and the data is worthless.
Run it at a speed you can actually think at
Maximum speed is for covering ground in a setup you already execute cleanly. When you are training a decision, run slow enough to notice yourself making it.
Review before you close the tab
Five minutes, three questions: did I follow the rules, where did I deviate, what was happening when I did. The last one is the useful one — deviations cluster, and the cluster is the thing to train next session.
Backcandle records the fills and computes the session metrics automatically, so the review is about the decisions rather than the arithmetic.
What to point a session at is deliberate practice for traders. When you are ready, start one.
