A Heikin Ashi Red Trend means at least seven red Heikin Ashi candles in a row. Heikin Ashi candles average the open, high, low and close of each bar with the previous candle, which filters out noise and makes trends easier to see. A long series of red candles shows a steady downtrend; trend followers often stay out or short while the candles remain red and watch for a green candle or shrinking bodies as the first warning of a pause.
