Confidence Scores and A, B, C Grades Explained
The confidence score is the single number that tells a marginal setup from a strong one. It is worth understanding properly, because using it well is most of the value of the tool.
What the number actually measures
Each of the 27 modules produces a reading. Each has a weight, which depends on the strategy you have chosen and the timeframe you are on. MSP combines them into a score from 0 to 100.
So the score measures agreement. High confidence means trend, momentum, volume, structure and the higher timeframes are all pointing the same way. Low confidence means they are arguing.
The grades
A sensible way to use it
The mistake is treating every signal the same size. The score exists so you do not have to.
- Pick a base risk per trade you are comfortable with, for example 1 percent
- Take A grades at your full base size
- Take B grades at your base size or slightly under
- Skip C grades, or take them at half size while you learn what they look like
- Keep the same rule for weeks at a time so you can actually judge it
- Doubling size on an A grade because it "cannot lose"
- Taking every C grade because you are bored and the market is quiet
- Changing the rule after two losses
- Adding to a losing position because the score is still high
- Treating a high score as permission to move a stop
Why the score moves while you watch
The score is recalculated on each closed candle. Watching it tick between 62 and 68 is normal and means nothing. What matters is whether it is trending up or down across several candles, and whether it crosses the threshold that changes the verdict.
If you find the movement distracting, look at the grade instead. It changes far less often, which is exactly the point of having it.
When confidence is high but MSP still says no
This confuses people, and it is worth understanding. The score can be high while a hard filter is blocking the trade. Wide spread, dead volume and a ranging market all override the score, because a good idea executed in bad conditions is still a bad trade.
The why-lines will name the filter that is doing it. That is the fastest way to understand what is happening.
Common questions
What does an A grade mean in Market Structure Pro?
That the modules strongly agree with each other. It is a measure of evidence quality, not a guarantee of a winning trade. A grades are relatively rare.
Should I skip C grade signals?
Many experienced users do. A C grade means the evidence barely supports the call. Skipping them is a legitimate strategy and costs you very little.
Why does the confidence score keep changing?
It is recalculated on every closed candle. Small movements are normal. Watch the direction of travel across several candles rather than each individual reading.
