A Free Larry Williams–Inspired Study with Powerful Filters

At the request of many Larry Williams fans, here’s a 100% free custom study that automates the classic Smash Day pattern and layers in professional-grade filters—for a cleaner edge and sharper price-action execution.

🔍 What It Does

Smash Day Pattern Detection

  • Buy Signal: Yesterday closed below the prior day’s low.
  • Sell Signal: Yesterday closed above the prior day’s high.
  • Entry: Triggered on current day break of yesterday’s high/low.

🛠️ Built-In Filters for Precision

🔹 Extreme Break Filter (Toggle)
Requires the Smash Day bar to break the lowest low / highest high of a lookback period (3–20 days).

Recommended setting: 3–8 days, as Larry Williams often used this range to ensure the Smash Day truly “breaks” recent structure

🔹 Volatility Filter (Toggle)
Filters out setups where the Smash Day range is less than ATR × Multiplier (ATR 1–100, Multiplier 0.1–10).

🔹 Volume Filter (Toggle)
Optional filter requiring the Smash Day’s volume to exceed Average Volume × Multiplier (Period 5–100, Multiplier 0.5–5.0).

🔹 Trend Filter via Moving Average (Toggle)

  • Buy signals only allowed if price is above MA
  • Sell signals only if price is below MA
    (Fully configurable MA period: 5–200)

🔹 Arrow Offset
Control how many ticks above/below price the up/down arrows print (0–100 ticks).

🎯 Why Use This Study?

  • Removes noise by filtering out weak Smash setups
  • Targets high‑probability reversal setups, capitalizing on breakout exhaustion
  • Fully customizable and non-repainting
  • Designed for both intraday and swing setups (ideal for 1‑hour & Daily charts, but fully configurable to any timeframe)
