DislikedAfter comparison with Metatrader 4 and Trading Station, the result is the same. So it is not a bug. This is caused by the number of candles. A trendline in only valid for its timeframe. Higher is the timeframe, better is the trendline. Sorry for that.Ignored
meaning if you draw in the H1 chart .. then switch to M5 and zoom out .. the line will re-ajust
that's is simply because the data is not there in the M5 chart until you zoom to the point where the line is pinned on
