if you follow simple set ups like reversal bars , two bar reversals, inside bar/s , double bottoms and double tops....you cannot lose. These have been used by traders for hundred years
if you see the write up by Brooks concerning set ups and follow what he says strictly you cannot lose: why traders have problems with Brooks is that brooks talks about a lot of things which are subjective.
study what Brooks says about set ups and what is the context, in which they are valid, you will never lose.
the main important thing about this is that it gives you a clearly defined stop loss which is extremely tight and small :many traders us methods which do not give these same critical advantages.
If you do not have tight stops it does not matter if you have the best system in the world or if you have perfect market knowledge.
this is my personal experience: i lost because i did not focus on the set ups and trade them:
all of the set ups give the opportunity of a one bar risk and profit relatively huge so even if you get the context wrong sometimes you will still not lose.
set ups give you a system and remove the emotional and subjective aspects from your trading.
it took me a long time to figure why i was losing : focus on non subjective aspects of trading. I found Brooks good personally.
but there a hundred others who describe the same thing as Brooks, so it does not matter, who you refer to, wrt to these simple, time tested concepts : reversal bars, two bar reversals, inside bar/s, DB, DT, are all defined in the same way by all hundreds of teachers .
Brooks goes a step further by defining micro DB, DT .....and a few other things so this is why i prefer Brooks
