… if I give some examples:
ADR - I like this very much, cool concept and tool
Pivots & TT - again my favourite (but I use only TT and central pivots, I dont use R1/S1, MR1/MS1, R2/S2 etc. at all)
Kill Zones - time of the day, also my favourite tool, but again, I dont trade London Close strategy, but use it as exit point very often in intraday trading.
OTE - I like it, but dont use it at all, I use something very similar, candlestick patterns for entry trigger and supply/demand areas, but it is basically the same.
Fibo extensions - I dont use 1.27 ext. or very rarely, but like very much 200% extension idea for targets, S/R levels inside 1.618 - 2.0 extensions are also my favourite.
SMT - it is very cool as additional tool for trading decisions, I dont use it very often, but I like very much SMT divergence to support my swing and longer term trades.
Market Flow - I almost dont use this tool, sometimes I look at it if Im not sure about situation. I found only one good thing in this tool and thats the point where market flow changed its direction.
I dont use fundamentals and COT at all. In my case it always leads to analysis paralysis. Of course I use economic calendars and understand what the reports say, but Im not able to trade succesfully based on fundamentals.
EDIT: I use fundamentals in one special case…If media (TV, newspapers, etc.) and people who has nothing to do with trading start to talk too much about financial markets and panic, it is always good time to look for some trade in exact opposite direction, than what others do.
Do you know this old joke?
