§ The Strategy

Sell where price doesn't go.

Two independent models pick the strike. The OR Bias greenlights the day. You execute.

GREENLIGHT OR Bias First 30 minutes HISTORICAL IMPLIED Two levels, one zone Best premium & distance SELL EXECUTE Credit spread At the indicated strike +100% −300% BINARY EXITS Hold or exit ~91% BACKTESTED Win rate

The path

Entry to exit,
in five moves.

I
9:30 — 10:00 AM

The OR Bias reads the open.

The first 30 minutes of the session are evaluated against a set of structural signals. The result is a single colored dot on the opening candle — the day's verdict. Green or yellow, you trade. Orange, step to a more conservative level. Red, sit it out.

II
Strike Selection

The chart shows the strike.

Historical percentile data and implied move are calculated independently. The indicator plots the strike with the best balance of premium and distance — the number is already on the chart. No guessing. No delta-chasing.

III
Premium-First

Start at 95%. Step out if needed.

The 95th percentile level carries the most premium — it's the first look on every session. If the OR Bias signals caution, the framework steps out to 98%, then 99%. Premium first, but only where the math and the day both agree.

IV
Hold

Hold for full credit.

The statistical edge is front-loaded. The entire premium is earned at expiration when price stays out of the zone — which, statistically, it almost always does. Early exits are yours to take if risk comfort calls for them. The framework doesn't require them.

V
Cap the Loss

If it goes against you — exit at −300%.

A clean, predetermined number. No hoping, no rolling, no averaging down. The math handles the winners; the stop handles the rest.

Why the levels work

Two levels.
One zone.

Each model produces its own level — one from real price history, one from today's implied range. The indicator plots the strike that balances the most premium against the most distance.

I · HISTORICAL Looks backward Real open-to-low moves, deep history, the exact symbol. 95% II · IMPLIED MOVE Looks forward The options market's forecast, dynamic with today's volatility. 95% ← FURTHER FROM PRICE PRICE → the zone HISTORICAL the backward look IMPLIED the forward look PRICE current Two levels. One zone. The strike is the best balance of premium and distance.
The Output

Two levels, one zone. Premium and distance, balanced.

The day's verdict

A single dot tells you
how to trade it.

The OR Bias scores the first 30 minutes across six signals and returns one color on the opening candle.

Trade
Premium level — 95%.
Trade
Still green. Take the setup.
Step Out
Move to 98% or 99%.
Sit Out
The math says no.

The ladder

Three levels, same math.
Escalating safety.

Every level on the chart is built the same way. You just pick the one the day justifies.

The outcomes

Two clean exits.
Nothing in between.

No scaling out, no rolling, no averaging down. A decision framework this simple keeps emotion out of the seat.
