Observers before storytellers

We teach traders to describe what the book is doing before they invent a reason for the move.

Logic Mosaic Field Limited

Logic Mosaic Field Limited was established in 2016 in Hong Kong. The firm began as evening tape-reading clinics for a handful of proprietary traders near Kowloon Tong who wanted language precise enough for risk meetings. Over the following years the clinics grew into the Order-Flow Reading Intensive, mentorship sessions, and commissioned desk briefings.

Our working premise has stayed narrow: technical analysis training is useful only when it trains attention to resting liquidity, aggressive prints, and unfinished auctions. We do not sell signals, copy-trading, or managed accounts. We sell time with instructors who have sat the book and can interrupt a narrative when the ladder disagrees.

How we work

Classes stay small. Live review beats slideshows. Journals are expected. Traders leave with checklists they can defend, not mottos. Studio sessions run from our space at Festival Walk so participants can step away from their own screens and watch the same tape together.

Values we keep visible
