what’s the best number of bars on a chart
enough for displaying at minimum 2/3 of the previous cycle (bullish/bearish) and the whole of the current cycle no matter what timeframe (?)
R and S lines also help for super-size zooming in if this is the case
Depends heavily on your trading style
Are you a scalper, looking to get in & out quick?
Do you prefer taking longer positions, which you’d like to hold for a few weeks?
Does your trading plan call for spotting a signal on a higher timeframe, than zooming down intraday to find an entry?
This is like asking how much cream & sugar I should put in my coffee to a room full of 250 coffee drinkers.
Really depends on your own style.
