The Ctreder Smart SMA Indicator is a technical analysis tool that integrates a Simple Moving Average (SMA) line with real-time crossover detection. It monitors price action on each candle to identify two key conditions: a bullish crossover, when the price closes above the SMA after previously closing below it, and a bearish crossover, when the price closes below the SMA after previously closing above it. Upon detecting these crossovers, the indicator provides visual signals by drawing green up arrows below the price for bullish crossovers and red down arrows above the price for bearish crossovers. Additionally, it issues alerts including sound notifications via a customizable .wav file and text alerts displaying "BUY" or "SELL" in the chart's top-right corner. This combination of SMA visualization, crossover detection, and multi-modal alerts supports traders in identifying potential trend changes efficiently.
