here is a handy tip for all when looking for signals to trade only load up 30-50 data points the reason trading signals recquire you to get in close to the price action.however,p/f can crowd the chart so..trading signals will recquire a different visual optimisation.ie box size and reversal to find the best signals to trade from to make life much more profitable the watchlists should be set up with possible trading signals only....then do the analysis after you have confirmed a decent set up.this means you are ready before market opens exit signals..these should only have 10-30 ish data points.ie you want to get near the action to look hard for that exits
by loading fewr data points we can then look hard at the trend going into the day and we are on notice to go long 30 min dow futures
if you load ...say 50 data points and you want to look further back.ie backfill..it will make you go to a higher time input for a longer look back period that does make life alot easier ..imho
played around a bit and 120 data points show the last 1-2 trends well so..a long term chart ..as many data points as you want..then 120 ish to pick up the latest trends and then 30 for breakout signals so..day trading long term chart...then 120 data points /60 or even 30 min then 30 data points /5 min for signals..1 min if further confirmation needed this can be applied to bar/candle aswell it does save alot of time with doing analysis
