A simple indicator of trend by using 3 EMAs of multiplies of 2, 5 and 10, filtered by standard positive/negative directional movements (DM) which are the base of Average Directional Index (ADX).
The "Trend Strength" option is included to set the EMA multipliers and also the variation between DM+ and DM- which interpret the trend as a weak or a strong one.
Note that the markers only point to almost the beginning of the trends and just change the direction when the opposite trend is detected.
