Color-Changing EMA 8 (Stateful) + Buy/Sell

This indicator is a state-based micro-trend detection engine built around the Fibonacci EMA pair 8 and 21, designed to reveal real momentum shifts at the earliest statistically valid moment. Instead of simply coloring the line based on price position, it analyzes acceleration and directional consistency, meaning it detects when price is actually gaining or losing force, not just moving up or down. This makes it especially effective for scalping, short-term trend riding, and momentum reversals inside active market sessions.

The color-changing EMA line operates as a three-state trend machine. Green indicates confirmed bullish acceleration, red indicates confirmed bearish acceleration, and black represents a neutral or undecided momentum state. These colors are not cosmetic; they only activate after two consecutive bars confirm the same directional acceleration, filtering out one-bar fakeouts and random noise. This debounce logic is what allows the indicator to flip cleanly at real turning points instead of constantly repainting.

Buy and Sell signals are generated using a non-repainting state transition system. A Buy signal only appears when the trend state flips from confirmed bearish to confirmed bullish. A Sell signal only appears when the trend flips from confirmed bullish to confirmed bearish. This prevents repetitive signals in the same direction and ensures every tag represents a true regime change, not a continuation spam signal.

Each Buy and Sell label is intentionally offset back one candle, placing the signal directly on the bar where the momentum shift first became structurally valid — not on the reaction candle afterward. A matching vertical line is drawn through that bar to visually anchor the transition point in price. This allows traders to clearly see where momentum actually flipped, making back-testing, execution review, and real-time entries far more precise.

Because this indicator tracks acceleration instead of trend lag, it excels at capturing the natural humps and valleys inside trending markets. It is particularly effective on instruments with clean liquidity behavior such as Gold, BTC, ETH, major futures, and index products. In active volatility conditions, this allows traders to ride multiple micro-moves within a single macro trend.

This indicator does not predict the future; it detects when the market has objectively changed state. It is a momentum confirmation engine, not a guessing tool. Like all momentum systems, it performs best during expansion phases and should be used with caution during low-volatility chop, overnight compression, and pre-news conditions.
