Nasdaq-100 (Oct 2023), Turtle System 2

The rules

Buy at the next minute's open after an hourly close tops the highest high of the last 55 completed sessions, with a stop 2N below the decision close, where N is the 20-session Wilder average of the day's true range. On each session's first bar the stop rises to the higher of 2N below the fill and the lowest low of the last 20 sessions, and the stock is sold if it is already at or below it. Long only, 1% of the account per stock. It needs 55 sessions on file, so its first entry can come on December 19, 2023.

Read this before you trust it

This basket uses no hindsight: the Nasdaq-100 as it stood the day before the test began, from its published membership. Alphabet is held once, as GOOGL, and seven members are out because they stopped trading here before the test ended: SGEN, SIRI, ANSS, WBA, AZN, EA and WBD. Its runs start with $1,000,000 so that a 1% share buys whole shares of the dearest members; at $100,000 a stock above $1,000 could never be bought. Picked on November 8, 2026 by a rule written before any run: published evidence, yearly costs at most a quarter of the published gross return, buildable in Orbital, and the source's own parameters. Every rule is published whatever it shows. Orbital's engine cannot rank entries for a program that decides more often than daily, so instead of the source's position cap each stock gets an equal share and every signal is taken. Orbital's minute data starts in September 2023, so the session records start on October 2, 2023: early in the test a record is a short one. The selection expected it to trail SPY: it is flat for the first seven weeks.
