Stocks-in-play breakout

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.

Reserved, not trading: $45,000 of the INTRA1 Alpaca paper account is set aside for it. The published 5-minute opening-range breakout on the day's stocks in play (Zarattini, Barbon and Aziz) without its stop, held to the close, as protocol 8's research tested it. Its ranking needs a real-time consolidated feed that this account does not have. It stays reserved until one is available and has been checked against SIP on a live morning, and even then its entries in the 9:35 minute are at risk.

Universe: common stocks opening above $5, with a 14-session average volume of at least 1,000,000 shares and a 14-session average true range above $0.50.
Stocks in play: the 9:30–9:35 bar's volume at least 100% of its mean over the previous 14 sessions that have one (at least 10); in each half of the list, which a hash of the ticker splits in two, the 10 with the highest ratio.
Entry: from 9:35, a buy stop at the first 5-minute bar's high if it closed up, or a sell stop at its low if it closed down; a doji keeps its place and trades nothing.
Exit: at the close. There is no stop.
Size: each place gets a tenth of its half's book, sized as if the stop were one ATR away: 1% of the place at risk, at most 4 times the place.
Data: the ranking needs the consolidated volume of the 9:30–9:35 bar as it ends; the free real-time feed (IEX) carries a few percent of it and none of the opening auction.
