Reading trading conditions: what a 0 to 100 score tells you

Which way the market leans is only half the morning's question. The other half is whether today is a day worth trading at all. This guide explains what a trading-conditions score measures, how to read the 0 to 100 scale band by band, and why the most profitable answer some mornings is to close the laptop.

Direction is not the same as tradeability

Here is the experience every intraday trader knows. You call the direction right, the market does end the day higher, and you still lose money, because the path from open to close was a saw blade. Price whipped through your stop twice before going where you said it would. You were right about the destination and broke on the journey.

That is the difference between direction and conditions. Direction asks: up or down by the close? Conditions ask: when the market moves, does the move follow through, or does it snap back and punish everyone who joined it? Setups that work beautifully in trending conditions bleed in chop, and no entry technique fully rescues a day that refuses to follow through.

What the score measures

The conditions score compresses that second question into one number from 0 to 100. Each morning's score ranks the coming session against the past year of them. A model trained on a decade of sessions reads where volatility sits now, how far the overnight and pre-market ranges have already travelled, the shape of the VIX curve and what the calendar holds, then places today on that scale. Higher means cleaner: movement with follow-through. Lower means the tape is likely to fight both sides.

The three bands

• DIRECTIONAL, 80 and above. The cleanest days. Moves are likelier to extend than to reverse instantly, and trend setups get the conditions they were designed for. This is not a promise the day is easy, only that the wind is not in your face.
• MIXED, 30 to 79. Tradeable, with tolls. Some follow-through, some snap-backs, and the difference between a good and bad day is selectivity. Many traders treat mixed days as A-setups-only days: the plan trades, the maybes stay on the bench.
• CHOPPY, below 30. The tape is likely to rotate in a range and hunt both directions. Breakouts fail, stops on both sides get collected, and the edge in most directional setups degrades toward zero. These are the days the score exists for.

The case for not trading

Standing aside feels like doing nothing. It is not. A day you don't trade costs you nothing, and on a low-scoring day "nothing" frequently beats the alternative: commissions paid to be whipsawed, stop-outs in both directions, and the worst cost of all, the tilted state of mind you carry into tomorrow after a day of death by paper cuts.

This is also why the score is deliberately allowed to be discouraging. A conditions tool that mostly says "great day to trade!" is a marketing tool. The honest version has to be willing to tell you, some mornings, that the fair reading of the evidence is: not today. The specific days that tend to earn that answer are laid out in when not to day trade.

The size of the day

What the score does not tell you is how big the day will be, so the engine says that separately: the largest one-way run it expects in ES and NQ, in index points, against each instrument's 20-day average range. A clean day worth 40 points and a clean day worth 90 both score well, and they are not the same trade. Our guide to how many points ES and NQ move in a day covers how to read those figures and size a trade against them.

The printed score itself does not get rewritten: the morning read stands and gets judged as issued, which is the same honesty rule the bias grading follows.

Using conditions and bias together

The two numbers answer different questions on purpose, and they combine naturally. The bias says which way the evidence leans; the conditions score says whether the day will let you use it. A bullish call on an 84 is a different proposition from the same bullish call on a 24, and treating those two mornings identically is leaving information on the table. The full framework for folding both into your own setups is in using a daily bias as confluence.

As always: this is education about reading a measurement, not advice about what to do with your money. The score describes the day. What you do with the day is, and should stay, your own plan's job.
