Paper trading, not investment advice. Every account and book on these pages trades paper money: the Alpaca paper accounts DAILY ($1,000,000 from Sep 30, 2026), INTRA1 ($100,000 from Sep 30, 2026) and INTRA2 ($100,000 from Sep 30, 2026); the simulated books SIM-TT ($100,000 from Sep 29, 2026), SIM-V2B ($100,000 from Sep 28, 2026) and SIM-V2B-TOM ($100,000 from Sep 28, 2026), filled at the official close; and market-analysis's ledgers, one contract per position against a $100,000 reporting equity. No real money is at stake. Positions, trades and P&L are published the same day, as the engines record them, with each number's source and cost model labelled. Nothing here is a recommendation to buy, sell or hold any security, and nothing is tailored to you. Each strategy is a pre-registered experiment, read once on a date or at a trade count fixed in advance; until then its record says little either way. I may hold or have held positions in securities shown here. Markets can and do lose money.

The owner's level-to-level guide as written, with its 1-hour trend filter and its sector breadth filter. On SPY and QQQ, a 0DTE option is bought when a 5-minute bar touches a level zone and closes back on its side, and a 2-minute close then breaks that bar's high (a call) or low (a put). The nightly log prices each trade on the real 1-minute option bars; no order is sent. Logged beside V2 and F2 for information; it will not be evaluated as a test.

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.
Setup: a 5-minute bar comes down to within one tolerance of a zone and closes above it, after one of the six 5-minute closes before it was at least three tolerances above the zone. That sets up a call; a put mirrors it from below.
Trigger: a 2-minute close above the setup bar's high buys a call (below its low, a put), within 30 minutes of the setup bar's close. A close beyond the bar's other side cancels the setup, and a newer setup on the same side replaces it.
Filters: a call needs the 2-minute close above the 1-hour EMA20 and more of the 11 sector SPDRs above their previous close than below it; a put needs both the other way. The EMA20 is computed over the extended-hours 1-hour bars.
Entries: decided from 11:00 to 15:30 ET, with at least $2 of room to the next zone in the trade's direction before 14:00 and $1 after. 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 before 14:00 and $1 after. Its last trade must be at most 5 minutes old and from $0.05 to $0.66, or to $0.40 after 14:00.
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.
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.
