This indicator will paint a candlestick green (for an uptrend) or red (for a downtrend) regardless if the candlestick is bullish or bearish. There will be different shades of green or red depending on the strength of the trend. See in the pictures how the chart looks like with and without the indicator.
This is accomplished by calculating different averages of the openings, closings, high and lows of the most recent candlestick as compared to previous candlesticks. You can define how many previous candlesticks you want to consider should you want to visualize short-term or long-term trends.
Combine this indicator with another to define your entry and exit strategy or to compare different time frames of the same currency pair to see if the shorter time frame trend is consistent with the larger one.
