Time based trailing and break even stop could be beneficial during some market conditions. If the trade does not go anywhere it mostly reverses. Watching SQ breakout strategies trade for 3 years almost always you have a reversal and it gives everything back or the trades might even turn in to a looser. In most cases even if you have a trailing stop it has never been triggered due to the low volatility so I think having a time based trailing stop and/or break even stop could be very beneficial and give greatly improved portfolio performance during periods of low volatility.
