Introduction of indicators:

This index is mainly used to check whether the trading direction is correct:

• Red represents the rise, prohibits the sale, can buy or wait.
• Green stands for decline, no buying, selling or wait.
• Blue represents no trend, no prohibition.
• Trend: when the trend continues, the blue column appears, indicating the tendency is weaker, and the signal of trend reversal is given.

Core code interpretation:

      if((macd_main_buffer[i]-macd_main_buffer[i-1])>0 && (ema_buffer[i]-ema_buffer[i-1])>0)          {           Power_buffer[i]=1;//rise signal           color_buffer[i]=1;          }        if((macd_main_buffer[i]-macd_main_buffer[i-1])<0 && (ema_buffer[i]-ema_buffer[i-1])<0)          {           Power_buffer[i]=-1;//drop signal            color_buffer[i]=0;          }
