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.

Cost model

Alpaca paper fills, with no commission; Alpaca's SEC and CAT fees, charged by the day, are left out. Commission is estimated at $0.007 a share a side, the rate at the owner's own broker: the net P&L is the P&L less it; the P&L, the return, the P&L in basis points of the book and the R multiple are before it. The rule book's day return is the rule's own replay on SIP bars, after the research's own costs: $0.0035 a share a side in commission for the noise area and $0.007 for the other rules, and a cent a share of slippage on every fill except a resting limit order's and the noise area's exit at the close.

The rule's own trade

The rule replayed on its own bars, beside the account's fills.
