Nemo Statistical Bias Day of Week Win Rate

Does your market really lean bullish on Tuesdays? Stop guessing — measure it. Traders repeat weekday folklore for years without ever checking. Statistical Bias checks — on the actual history of the instrument on YOUR chart — and shows the result in a compact, always-visible panel.

▶ WHAT IT DOES

Over your chosen lookback, the indicator computes for each weekday (Monday to Friday) the percentage of days that closed up, and displays the full weekly profile in a clean panel — with today's weekday highlighted, so the relevant number is always in front of you.

• THE LEAN — has this weekday historically closed bullish or bearish for this specific symbol?
• THE CONTEXT — the whole week side by side, so you see which days carry a real tendency and which are coin flips.

Everything is computed from the symbol's own data, transparently. No curve-fit magic, no black box — descriptive statistics, honestly presented.

▶ KEY FEATURES

• Per-symbol analysis — EURUSD's weekly personality is not XAUUSD's. Each chart gets its own real numbers.
• Adjustable lookback — study the recent regime or the long-term character, and compare the two.
• Today highlighted automatically — zero effort to find the number that matters right now.
• Clean panel presentation, position and colors configurable.
• Any symbol, any timeframe. Negligible CPU cost.

▶ INPUT PARAMETERS

• Lookback depth — how many days of history feed the statistics.
• Panel position and full color settings.

▶ HOW TO USE IT

1. Load it on the instrument you trade and read its weekly profile once.
2. Use the lean as a BACKGROUND weight: "this pair has closed up on 60% of Tuesdays" is one more small vote for long setups on Tuesday — never a reason to trade by itself.
3. Re-check periodically: seasonal characters drift as market regimes change.

▶ WHAT IT IS — AND WHAT IT IS NOT

We build honest tools. This is descriptive seasonality — a measurement of historical frequency, not a forecast and not a guarantee. Past tendency does not predict tomorrow, and we make no profit claim. What we promise is honest arithmetic on real data, so YOU can judge. Use it as a soft bias filter alongside your own analysis. DEMO included — test it before you buy.
