Reading the Market

Observations on price, structure, and behavior

About this tag

Trading is mostly the boring parts. Position sizing. Order routing. What happens when a venue throttles your API. How a fill at the wrong price compounds over a thousand trades. The chart is the smallest piece of it.

This tag collects observations from running automated systems against live order books. The notes are descriptive, not prescriptive. They cover how decisions get made under uncertainty, how execution quality degrades during volatile sessions, and how the market behaves differently at 03:00 UTC than at 14:00 UTC.

Recurring themes:

  • Execution: slippage, partial fills, latency, venue-specific quirks.
  • Decision frameworks: how to think about trading when most signals are noise, and how to size around the ones that aren't.
  • Market dynamics: liquidity behaviour, regime shifts, the gap between what the chart implies and what the book actually holds.
  • Failure modes: the trades and systems that lost money, and what was learned from looking at the logs afterward.

The framing is observational. A bot ran, an outcome happened, the data was reviewed. That is the loop. There is no claim that any of this generalises to a different account size, a different venue, or a different week.

If you are looking for a trading framework to copy, this is not that. If you are looking for thinking out loud from someone who watches order flow for a living and writes down what surprised him, the entries here should be useful.
