What it is

A trading terminal that teaches you.

You sit at a real chart and make real decisions under uncertainty. As you do, the Lab watches how you decide — and coaches you toward the process that actually makes traders profitable.

Unknown markets, no hindsight

No cheating the outcome.You never know the stock, the year, or the condition until the session ends — so you decide under genuine uncertainty, not by pattern-matching a chart you’ve already seen.

A live decision coach

Caught in the moment.It flags the behaviour that quietly loses money — no stop, revenge entries, widening stops, overtrading — and reinforces the good habits in real time.

Scored on decisions, not luck

Process over P&L.Your headline number is a Decision Quality Score, not profit. Win recklessly and it says “that was luck.” Lose with good process and it says “keep going.”

A structured curriculum

Twelve guided drills.Four modules — risk, booking losses & profits, psychology, reading the market — each teaching a concept, then dropping you into the exact drill for it.

Every timeframe

5-minute to daily.Practise from fast intraday decisions to slower positional ones across 5-minute, 15-minute, hourly and daily bars. Each timeframe genuinely feels different.

Progress that compounds

It remembers everything.A weakness heatmap, XP for discipline, a daily streak, missions and badges — so you always know exactly what to work on next.

How a session works

Trade → get coached → learn → repeat.

1

Pick a lesson

The concept is explained, then the terminal loads with the matching market & objective.

2

Make decisions

Go long or short, set stops and targets, manage the trade as the chart moves live.

3

Get analysed

Every decision is logged and scored. The market is revealed; the coach tells you what you did well and badly.

4

Advance

A mentor note hands you the one thing to fix and the next rep — one lesson at a time.

The usual approach

Watching, not doing

Passive content that feels like progress, then leaves no skill behind when the market moves.

  • Hours of videos you forget
  • Backtests with the answer already visible
  • Celebrates paper profits and lucky runs
  • No feedback on your decisions
