The functionality of the Trend Trader v1.3 is the same as v1.2, however, we have changed the code entirely so the EA will use an external indicator (similar to NonLagMA EA for MT4). The previous versions (1.1, 1.2) didn't have the need for an external indicator, but they proved to be a little too slow when attaching the EA to the chart and/or changing the timeframe. Therefore, we have decided to make this similar to the NonLagMA EA, that also proved to be a very reliable and stable expert advisor.
