SC MTF Williams Percent Range for MT4 with alert

What is Williams %R?

Williams %R (Williams Percent Range) is a momentum oscillator developed by Larry Williams that measures the level of the closing price relative to the high-low range over a given period. Values range from -100 to 0, where readings near 0 indicate overbought conditions and readings near -100 indicate oversold conditions.

Williams %R is closely related to the Stochastic Oscillator but inverted. It is particularly useful for identifying turning points in the market. Traders typically watch for crossings of the -20 (overbought) and -80 (oversold) threshold levels to generate buy and sell signals.

Features:

• Visual signal markers with arrows and vertical lines
• Three independent signal buffers with configurable triggers
• Signal detection options: direction change, level cross, peak/valley
• Configurable alert functions for each signal (email, push, sound, popup)
• Multi-timeframe (MTF) capability with interpolation methods
• Histogram or line drawing mode
• Multiple color modes (simple, direction-based, level-based)
• Custom indicator call (iCustom) buffer access for Expert Advisor (EA) integration
