Definition 18.3 Market Making and High-Frequency Trading · Capítulo 18 — News and Event Trading

Spread less mark-outs earned by quoting from the re-entry time until two minutes after a release, in tick-lots, when post-release flow starts at twenty-one times normal and decays over thirty seconds and its mark-out starts at three ticks and decays over five; dashed, a market maker that never pulled its quotes, after its loss in the race. Data: hf_news.reentry_curve.
