How do you handle NY open inventory risk

NY open inventory risk — how do you handle it?

Carrying a London scalp into NY open has burned me more than the average loser. Spreads step wider, inventory flushes, and a tidy +0.6R can become −0.4R in a minute while I “just watch.” So I treat NY open as a risk event, not a new playground by default.

Current handling:
  • Default: flat or hard reduce 10–15 minutes before NY cash open if the trade thesis was London-session
  • Exception only if the idea was written as overlap-specific with wider stop budget
  • No adding size into the open print — ever
  • Journal tag: inventory_into_NY when I break this, for shame and stats
Do you flatten by clock, by P&L threshold, or by structure (e.g. only hold if stop is beyond a clear level)? Interested in rules that survive real size, not demo bravery. If I am already in profit and the thesis is done, I take the money before the cash open rather than “giving it room.” Room into NY open is often just donated expectancy.
