Confidence Scores Decoded

How to read a card’s confidence, calibrate your size, and avoid overbetting.

Confidence Scores Decoded

Confidence is a probability hint, not a promise

The confidence on a swipe card signals how strong the setup is relative to recent history. It’s not a guarantee; it’s a guide to how much you should risk, not whether you should abandon discipline.

How to translate confidence into size

  • Set a base risk/unit: e.g., 0.75% of account per trade on normal days.
  • Scale inside a band:
    • 50–60: 0.5× base
    • 61–75: 1.0× base
    • 76–85: 1.25× base
    • 86–90: 1.5× base
    • 90+: Rare. Keep it at 1.5× base, not “all-in.”
  • Never exceed your daily/drawdown brakes: If you’re near limits, size down regardless of confidence.

What makes a confidence score rise or fall

  • Confluence of signals (structure + momentum + liquidity health).
  • Recent hit rate of similar setups.
  • Volatility regime and spread quality.
  • Time decay (TTL): stale ideas lose edge and confidence.
  • Venue reliability: rejects or throttling drag confidence.
  • Market microstructure: wide spreads or shallow book reduce usable edge.

How to avoid overbetting

  1. Cap per-trade risk: Hard ceiling (e.g., 1.5% max) regardless of confidence.
  2. Cap same-idea stacking: If two cards are correlated, treat them as one position.
  3. Respect venue/asset limits: Thin books? Even high confidence gets smaller size.
  4. Honor daily brakes: Confidence never overrides risk stops.
  5. Adjust for volatility: If ATR doubles, halve size even on high confidence.
  6. Match RR: If RR < 1.3, keep size on the lower band no matter the score.

Quick read checklist before you swipe

  • Does the stop sit outside noise? High confidence with a too-tight stop is fake safety.
  • Is the RR acceptable? If target/stop is ~1:1, size small even at high confidence.
  • Is liquidity normal? Wide spreads reduce real edge.
  • Are you correlated elsewhere? If you’re already long similar beta, downsize.
  • Is TTL fresh? A stale high-confidence card is worse than a fresh medium one.
  • Is funding sane? High funding eats edge; size down.

How to react to outcomes without tilting

  • Hit TP at high confidence: Log it; confirm the model’s calibration. Don’t increase size beyond your band.
  • Hit SL at high confidence: That’s data, not betrayal. Stay within the band; revisit structure quality.
  • Hit SL at low confidence: Working as intended. Small risk protected you.
  • Expire without fill: Good—no fill at bad price. Wait for the next card.
  • Slip more than expected: Trade fewer cards during wide-spread windows or reduce band by 0.25×.

Calibration drill (15 minutes, once a week)

  1. Take last 20 cards. Bucket by confidence decile.
  2. For each bucket, note TP%, SL%, average RR.
  3. If a bucket underperforms, cap it to 0.75× base next week.
  4. If a bucket overperforms with tight stops, check slippage to ensure it’s real edge.
  5. Adjust band rules; write them down so you don’t improvise mid-week.

Common confidence myths

  • “High confidence means bigger stops are okay.” No—stop distance is structure-driven; size absorbs distance.
  • “Low confidence = skip all.” Not always; low can be fine with tiny size if RR is strong.
  • “Confidence replaces RR.” Never. Bad RR + high confidence is still a bad bet.
  • “One big win fixes variance.” Overbetting one card usually breaks the curve.

Mini playbook: news days

  • Treat all bands as half-size on major news days.
  • Only take cards with RR ≥ 2.0 and stops outside the news wick.
  • If spreads blow out, pause until they normalize; confidence scores assume sane microstructure.

Mini playbook: low-vol chop

  • Expect more fake breaks; prioritize cards with wider structure stops.
  • Keep size at 0.5–1.0× base unless volatility picks up.
  • Be comfortable passing more; confidence drops faster when TTL decays in chop.

FAQs

  • Can I ignore low confidence if I “feel” it? Feelings aren’t calibration. If you must trade it, trade it small.
  • Why not go 3× at 90+? Edge isn’t linear at the tails; capacity and variance explode. Protect longevity.
  • Does confidence equal hit rate? It’s related but also factors liquidity, vol, and recency of similar setups.
  • Should I stack two high-confidence cards on same asset? Treat them as one idea; split size, don’t double total risk.
  • What if confidence drops after I’m in? If structure and RR still hold, stick to plan. Avoid panic exits without signal.
  • Do funding/spread changes affect confidence? They should affect your size. High cost = smaller size even if confidence is high.

The takeaway

Confidence should tune your size, not override your rules. Pick a base risk, apply a simple banded scale, and never let a high number talk you into breaking your brakes. That’s how you stay in the game long enough for any edge to matter.
