GRMN, Oct 8, 2026 · Trading desk

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. In the DAILY account, shares one sub-book buys and another sells at the same close meet inside the account at the official close, and every leg on the larger side gets one average of that price and Alpaca's fill. 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, without dividends; the P&L, the total with dividends, the return and the P&L in basis points of the sub-book are before it. An open trade is marked at the latest official close, before commission, with the dividends paid so far beside it.

Entry value: $2,142.88
Exit value: $2,214.56
P&L: +$71.68
Dividends: $0.00
