Renko EMA-Scalper Zones is a lightweight, visual scalper indicator built exclusively for Renko 100-pip charts on the cTrader platform. It uses two Exponential Moving Averages (EMAs) to identify short-term trend direction and to highlight clean, tradeable zones. The indicator draws filled rectangles on the chart in four colors so scalpers can immediately read market bias and spot higher-probability entries without manual number-crunching.

What each color means

• Green rectangle — Bullish trend confirmed. Fast EMA is above Slow EMA and the EMAs are oriented upward. Use for short, trend-following longs.
• Purple rectangle — Buy-entry zone inside a bullish context. Indicates a short-term pullback or consolidation within an active bullish trend that may offer a scalping entry.
• Red rectangle — Bearish trend confirmed. Fast EMA is below Slow EMA and the EMAs are oriented downward. Use for short, trend-following shorts.
• Yellow rectangle — Sell-entry zone inside a bearish context. Indicates a short-term pullback or consolidation within an active bearish trend that may offer a scalping entry.

How it works (logic summary)

1. The indicator computes two EMAs (Fast and Slow) on a Renko 100-pip chart and assesses their relative alignment and slope to determine trend direction.
2. When EMAs indicate a clear bullish alignment and momentum, the indicator plots a Green rectangle that spans the trend region. If a short consolidation or pullback appears within that bullish region, the indicator plots a Purple rectangle to mark a buy-entry opportunity.
3. The same logic applies in reverse for bearish conditions, producing Red (trend) and Yellow (entry) rectangles.
4. Rectangles are drawn as zones (not single bars) so scalpers can visually assess where to time quick entries and exits.

Recommended settings (scalper defaults)

• Chart type: Renko
• Renko brick size: 100 pips (indicator designed for this brick size).
• Sensitivity / detection — an adjustable parameter controls how strictly the indicator requires EMA alignment before plotting trend rectangles (lower = more signals; higher = fewer, stronger signals).
• Rectangle opacity — adjust for visual clarity over price bars.
• Session filter — recommended to restrict to high-liquidity hours for scalping.
• Max zone width (bars) — optional limit to avoid overstretched zones.

Usage guidance & scalper rules

• Treat Green/Red rectangles as trend confirmation. Prefer trading in the direction of the coloured trend zone and avoid aggressive counter-trend scalps when a trend rectangle dominates.
• Use Purple/Yellow rectangles as scalping entry windows within the confirmed trend — look for a quick micro-structure trigger (e.g., momentum bar, breakout of a small consolidation) before entering.
• Targets should be tight and realistic for scalping (small multiples of your stop). Use fixed pip targets or min-bar confirmations depending on your risk profile.
• Place stops beyond the recent micro-structure low/high or outside the entry zone; scalping requires disciplined, small losses.
• Combine with volume/price-action confirmation (if available) and trade only during active sessions.
• Backtest visually on your instruments — Renko 100-pip favors volatile pairs and instruments where 100-pip bricks produce useful price structure for scalping.
