I can only agree with @Mumpsimus
above. He makes some very sound points and says it in his first post
whatever you look at, whether its price action or indicators its all relative to what works for you.
I would hate the idea of trading with price action unless i could quantify everything. if you are trading pullbacks in a trend, i've got to be able to define what a trend is, how deep is the pullback. I cant do that without a quantifiable number, which there will be a indicator for.
but that doesnt mean the indicator also isnt subjective. Just because a moving average has a value, which period of moving average (10, 20, 50) what type (simple, exponential, weighted). someone is always doing something different. its what works for you.
I dont give a toss for anyone who says dont trade with indicators as its lagging. what an absurd comment. Just because i can, they can't doesnt make something wrong or right. If it works for me, its right!!
I'll know when it stops working because statistically i will have some reference point. how many trades produced a winning trade and how many losing trades did i have in a row. over a certain sample size, i'll know whether im going wrong. the subjectivity of what i do isnt guiding my decision because every one of us will likely be doing something different.
