Floor 6: The Model
The Liquidity Engineer
The Liquidity Engineer is the boss at the end of the Core tier. Across five rounds on one simulated session, a talkative market maker pushes you toward stops at the obvious levels. You answer with order tickets, checked against four written desk rules. It tests stop placement and patience together.
Free, with a verified email address. An account saves your progress, and floors and tiers open as you level up.
What it teaches
Stop placement and patience under pressure.
- Seeing your own stop as part of a liquidity pool.
- Placing a stop beyond where a sweep would reach, not at the first tidy line, and accepting a smaller size for it.
- Passing as a decision with a score, not as a failure to act.
- Holding a trade as planned: no wider stop, no adding, no early close.
How a round plays
- One simulated USD/JPY session, five decisions. Equal lows and equal highs are marked, and your four desk rules stay on screen.
- The rules: a stop 10 to 25 pips beyond the marked level, a target of at least 2R, pass when no ticket fits, and hold once you are in.
- Each round offers order tickets with their numbers: a tight stop, no stop, a pass, or later a wider stop, an add or an early close.
- The market maker gives confident, bad advice. Check each ticket against the rules, not against how sure he sounds.
- Progress comes from the discipline of the choice over the five rounds, including good passes, never from how a simulated trade ends. About four minutes.
How it is graded
Each round is decided by the four desk rules on the card: stop distance beyond the marked level, minimum reward, pass when no ticket meets both, hold once in a trade. A correct pass counts as much as a correct trade, and the profit of the simulated trade counts for nothing.
The honest note
The boss is a teaching device. Real markets are not hunting one retail stop, though crowded stop levels do get traded through for ordinary reasons.
