Same-session exits from multi-day open-close codes

One procedure from code to close

Editorial: treat a string of prior closes plus today's open as one complete procedure. Encode the open-to-close sequence, decide at the open whether to take a rule-based entry, wait for an opening-range breakout, or stand aside, and lock the same-session exit before any historical test begins.

A historical enumeration covered every two-, three-, four-, and five-day open-to-close sequence on T-bond futures from 1978 through 1987.

How the plus-minus code is read

In the plus-minus code, each plus or minus marks an up or down close versus the prior close, except the final sign, which marks that day's open and the trade entry.

Every tabulated sequence entered on the open shown by the last sign and exited on that day's close, and the tests used no stops.

Worked buy setups

The three-minus sequence means two lower closes and then a lower open. The illustrated long is taken on the third day's open and closed out on the third day's close.

One listed buy setup is three higher days, one lower day, and a lower open, framed as a defined upswing with a one-day counter move and a lower-open entry.

Breakout stops, session choice, and overlays

A suggested early-session tactic is to rest entry stops just beyond the open in the direction of the opening-range-breakout bias.

Illustration charts should use day-session opens, because the study is specified for day-session opens rather than night-session opens.

Expanding or contracting daily ranges relative to prior days can be added to the basic close-and-open sequences as a further filter.

Suggested context overlays include support and resistance, angles, and trendlines, plus watching price action around the open before committing.

The sequences are presented as a research starting point for mechanical system work, not as a method applied rigidly trade by trade.
