If MQ Trend plots aren't behaving as expected, check that you're not using too small of an ATR_Mult input. In general, you want to avoid anything less than 1. If you set this value closer to 0, then you may see cases where, for example, price closes below the bullish trend dots and doesn't get recognized as a time to reverse, along with other unexpected behaviors. Try using a number that's higher than what you have - preferably greater than 1 - and see if the problem resolves. The default recommended value for ATR_Mult is 4.
