Choi Yejun and the Incheon chart room

Choi Yejun spent 2014 to 2016 on a Seoul cash equities desk, keeping a paper log of which pullbacks the desk actually respected in the afternoon. The log was not a product. It was how she stopped arguing about a ratio when the argument was really about the swing.

In 2017 she registered Ponder Mosaic and took the room on Asian-game-daero so people who watch the Korean cash session could study after the close, without a screen full of other people’s lines. The first year was a single Tuesday table. Students brought their own prints.

In 2019 the Saturday extension clinic was added, after too many evening sheets tried to project a target before the impulse had finished. The clinic still refuses a projection that starts too early. In 2022 private mentorship was capped at four hours so the room would stay a study and not drift into a standing arrangement of levels.

Nam Kyungmin has been the chart assistant since 2021. He lays the wall print on the rail before the door opens and keeps the spare sheets. He does not lead the marking.

How the room works

Technical analysis training here means a pencil, a named swing, and a sentence another person can repeat. Fibonacci retracement and extension techniques are taught as marking habits, not as a list of ratios to memorise. A level without a swing sentence is erased before anyone leaves.

Orders stay with each student’s broker. The room does not hold accounts, and it does not send levels out after the evening ends. What you take home is the paper you marked.

The values are plain. Say the swing before the ratio. Prefer a sparse sheet. Treat an extension as a reference. Write the cancel note while the chart is still quiet. People who want a signal list are pointed back to those four sentences and, if that is not the work they want, they are better served elsewhere.
