Paper trade 0DTE first

Why paper first

A 0DTE contract expires the day it is bought. There is no waiting for a thesis to mature and no recovering from a bad entry next week. A wrong read, a badly chosen strike, or a target set beyond the day’s plausible range is settled by the close, at up to the full premium. Repeated daily, that is a fast and expensive way to discover that a process has no discipline in it.

Paper trading moves that discovery to where it costs nothing. The process can be run exactly as it would be run with money: pick stated before the open, graded by a fixed rule, recorded whether it worked or not. What is being tested is not a broker account. It is whether the person or system making the pick can state a falsifiable claim each morning and accept the grade each afternoon.

What paper grading can teach

Whether a read has any signal at all. A target either gets touched or it does not. Across enough days, a graded record separates a read that tracks the day’s movement from one that is noise with commentary attached.

How the path behaves, not just the ending. Grading both the intraday peak and the expiry value against the entry shows whether a pick tends to work early and decay, or arrive late, or never arrive. In this ledger, one graded day was a win on target touch that returned -5.2 percent held to expiry. That single row teaches more about exit questions than a month of win rates.

Whether the rules survive contact with losing days. A process that quietly changes its definitions after a loss was never being tested. Frozen rules and an unedited record are what make the losing days usable evidence instead of embarrassments to be revised away.

What paper grading cannot teach

This part is stated plainly, because it is where paper records mislead.

Paper grading is not execution. The ledger grades off recorded market prints: the contract’s opening print, its intraday high, and its value at expiry. A real order does not receive those prices by right. It receives a fill, at a bid or an ask, in a queue, possibly in part, possibly late. On a fast 0DTE contract the difference between the print on a chart and the fill in an account is real money, and no paper record contains it.

Slippage and spread are not paid on paper. 0DTE contracts can carry wide spreads relative to their premium, and the spread is crossed on entry and again on exit. Paper returns pay it zero times. Real returns pay it every day, win or lose.

Nothing here tests behaviour under real loss. Watching a paper contract expire worthless is an observation. Watching a real one do it is an event, and events change behaviour: exits get moved, size gets changed, rules get renegotiated mid-session. A clean paper record is evidence about a read. It is not evidence about the person who would have to execute it.

How this ledger does it

The 0DTE Ledger began on Thursday, 22 October 2026. One 0DTE QQQ pick is posted before the open each market weekday and graded the same afternoon. A day is a win if QQQ touches the stated target intraday in the regular session, and a loss otherwise. Graded returns are measured off the contract’s opening print. No orders are placed, no positions are held, and graded rows are never edited after the fact.

After seven graded days the record stands at 5 wins and 2 losses, an average max return of +132.4 percent, and an average expiry return of +36.6 percent. Seven days is a tiny sample, and the figures are presented as a record of those days, not as a result anyone should expect to reproduce.

The experiment’s assessment point is the scheduled eight-week review on Thursday, 17 December 2026. The review examines the graded record and the shadow exit track, and may propose amendments to the rules. It applies none by itself. Until a sample far larger than seven days exists, the correct conclusion about this process, and about any 0DTE process tested on paper, is the narrow one: the claims were stated in advance, and the grades are on the table.
