Read these first

  1. The hour before the bell is where most avoidable losses are prevented. A written pre-open checklist turns "did I remember?" into "did I tick it?", and its job is to catch the problems that are already sitting in your book before you place a single order.

  2. A trading day is not one long stretch of the same activity. Liquidity, volatility and the quality of your signals change hour by hour in a pattern reliable enough to plan around, and most of the discipline of running a book is doing the thing the current hour is actually good for.

  3. A corporate action rewrites the terms of something you already own, without you trading. Share counts, prices, resting orders, hedge ratios and price history all have to be rewritten with it, in the same way, at the same time, or your book and your systems quietly stop agreeing.

  4. A live risk screen shows you forty numbers and you have six and a half hours. This is which five actually predict trouble, how to read them in units of a normal day, and how to tell a bad hour apart from a broken book while there is still time to do something.

Then the rest
