How Confidence is calculated

What Confidence measures, the thresholds the model uses for win rate and profit factor, and the exact formulas behind the four rows on the Confidence tab.

What this does

Confidence asks one question: do you have an edge, and do you back it? It is the largest part of the VEXA Score, suggested at 40 per cent of the composite.

What the model weighs

Confidence is produced by VEXA’s AI rather than by a fixed formula, and the scoring guidance it works from is specific.

Win rate, judged against your trading style. The same percentage means different things to different traders:

StyleWin rate the model reads as good
Scalping40 to 55 per cent
Day trading50 to 65 per cent
Swing trading55 to 70 per cent

Profit factor, on a fixed scale: 2.0 and above is excellent, 1.5 to 2.0 is good, 1.0 to 1.5 is acceptable, and below 1.0 is treated as a problem.

Average P&L, where positive expectancy matters more than the size of any one day, and a rising trend counts for more than a flat one.

Consistency, meaning low variation in daily P&L. Steady beats spiky at the same total.

Direction, meaning whether the recent trading days are improving or deteriorating.

The model is told to be adaptive rather than mechanical. A trader with a 45 per cent win rate and a 3.0 profit factor is scored as highly confident, because the risk-to-reward is doing the work. A trader with a 70 per cent win rate and a 0.8 profit factor is not, because the losers are being allowed to run.

The four rows on the Confidence tab

The Confidence tab of the CDI breakdown shows four component rows. These are an explanation computed on your device over the last five trading days. They do not produce the score. The score comes from the AI. Expect the two to agree in direction and not always in level.

RowWeight label shownThe valueArrow up whenArrow down when
WIN RATE25% weightround(winRate)%60 or morebelow 40
PROFIT FACTOR35% weightprofit factor to 2 decimals2.0 or morebelow 1.0
AVG P&L20% weightΣ P&L / trades, rounded to the dollar50 dollars or morebelow 0
CONSISTENCY20% weightround(consistency)%70 or morebelow 50

Consistency has an actual formula:

CV          = standard deviation of trade P&L / |mean trade P&L|
consistency = (1 − min(CV, 2) / 2) × 100

A coefficient of variation of 0 gives 100 per cent. A coefficient of 2 or worse gives 0 per cent. Fewer than two trades in the window returns a flat 50, because there is nothing to measure variation against.

What you should see

A number to one decimal place, four component rows with arrows, a set of AI contributing factors each carrying a weight of critical, high, medium or low, and a written paragraph.

With no trades in the last five trading days, the component list is empty and only the ring and the AI text render.

If it doesn’t work

  • The rows disagree with the ring. They are meant to. The rows look at five trading days on your device. The ring comes from the AI, which reads a wider window, your baseline and your prior scores.
  • Profit factor shows a very large number. With no losing trades in the window there is nothing to divide by, and the surfaces handle that differently.
  • Confidence dropped after a profitable week. Check the consistency row. A week made by one outsized day scores worse than the same total spread evenly.
