The way to avoid the problems you outlined can be helped by knowing inside out the market you are trading.
The trades i posted do not have to be viewed as an "always in" strategy. Viewing the the whole trading day as if you were always in will help however, this will mean your trades would always happen under the same circumstances, these being when pressure changes from buying to selling and vice versa.
Your trading plan should also include a general time plan for the day, this includes knowing the times of day that indecision are likely to occur.
Another feature of your trading plan should be an analysis of when a trade is too risky to take using the "almost always in" method. This should ideally be based on price action and not just a monetary value. Including knowing where areas of strong S/R may occur again, and then calculating whether the initial risk of the trade is likely to result in a 1:1 reward or greater, and therefore whether it is worth the risk.
As for bases, it is rare to find prolonged bases that result in consecutive losses of your initial maximum risk, this is because the trailing stop will usually allow you to exit for a much smaller loss than your initial risk. Again avoiding bases due to lack of pressure only and not through accumulation can be helped with a time plan of the day.
Another way of minimizing losses during bases is to simply leave the market when you realise what is happening, then wait for the base to break out, and resume trading from an appropriate point, taking the same trade you would if you had been always in during the base.
Finer points of loss minimization come through contract management.
It is hard to explain some of the finer points of this strategy as they are personal trade filters that would be of no use to another trader.
The individual user has to develop the method around their own instrument, which will also help them gain a feel for the trading conditions at any time of day.
Sorry if that makes a complete lack of sense.
Even if this strategy turns out to not be right for you, the in market study needed to develop rules will be invaluable.
