0DTE zone-breakout option scalp

information onlybookforward-v5startedOct 2, 2026

What it is

A zone breakout, before 14:00 ET only and with the 1-hour trend. On SPY and QQQ, a 0DTE option is bought when a 5-minute bar closes through a level zone and price stays through it. The nightly log prices each trade on the real 1-minute option bars; no order is sent. One of the three rules that protocol 3, a search for a better entry under the owner's contract rule, took to its one-time held-out test. It is logged nightly for information only and will not be evaluated.

The rule

  • Levels: the previous session's high and low from 04:00 to 19:59 ET, its 09:30 open and its last regular-hours close, this session's pre-market high and low, and up to four spike-and-reverse wicks on the last 10 sessions' 1-hour bars. Taken in order of price, a level joins a zone while it is within one tolerance of the zone's lowest level, and the zone sits at the mean of its levels. The tolerance is 0.05 times the 14-day average true range as of the previous session.
  • Signal: a 5-minute close more than one tolerance above a zone, when none of the six 5-minute closes before it was more than one tolerance above it, is a break up; a break down mirrors it. The decision is the first 2-minute bar that starts within 10 minutes of the break and closes still more than one tolerance through the zone: a call on a break up, a put on a break down.
  • Filters: a call needs the 2-minute close above the 1-hour EMA20, a put below it; no sector breadth filter. The EMA20 is computed over the extended-hours 1-hour bars.
  • Entries: decided from 11:00 to 13:58 ET, with at least $2 of room to the next zone in the trade's direction. On each underlying, one position at a time, at most 4 a session, and one per zone and side.
  • Contract: 0DTE, at the $1 strike nearest the price $2 out of the money. Its last trade must be at most 5 minutes old and from $0.40 to $0.66.
  • Fill: bought at the open of the contract's first 1-minute bar from the decision, if it starts within 3 minutes.
  • Exit: a stop at 75% of the price paid. At twice the price paid, half is sold and the stop moves to the price paid; at three times, half the rest is sold and the stop moves to twice the price paid; each further multiple raises the stop to the one below it. Only the stop is checked on the entry bar, and a raised stop applies from the next bar. A stop sells at the lower of the stop and the bar's open. What is left is sold at 15:55, at the open of the contract's 15:55 bar or its last trade before then.
  • Costs: bought $0.01 above the bar's price and sold $0.01 below it, and $0.65 a contract a side; a ladder sale is at its level, once a bar's high is $0.01 above it. The log also records each trade at no costs, and at $0.02 a side with the same commission.
  • Sessions: none on a session that closes early, or when the underlying's bars cover fewer than 300 regular-hours minutes of the session, or of the session before it unless that one closed early.
