Hello Pratap
I trade BNF with 2 systems/methods one for positional and another for swing trading.
For positional system I use Daily Time frame and for Swing trading I use 15 Minutes Charts.
I had planned to trade them independently, but my testing showed that
its better to run the swing system only when it is in sync with the daily TF one.
These systems do not use any mathematical formula or derived logic,
do not refer to or use any other indicators, oscillators etc,
i did experiment with using many things including the VWAP or your multiple day rolling one,
but finally am sticking to the plain and simple trend following using OLHC and volume data.
The systems use a trailing line based on simple price action,
but again it is not something like those various kinds of super trend or kma etc.
MY SR levels are pure PA based, depend on bullish moves or bearish moves and range formations
The Daily is a SAR system, where as the swing one shifts to wait mode till next trigger comes along.
And yes both the systems wait for the close of candles on their respective time frame, so no BO/BD type of trading entries
Currently I am focused on the MM & Position Sizing aspect and testing various different ways for scaling in and scaling out of position.
Happy
