I tried to answer this a week ago but the screen locked up, will try again.
#1 - yes or you can use ATR or put the Fractal indicator on, an easy way to see hi & lows.
#2 - yes again but the green line has a direction and should be at 12 to 2 o’clock for long & 4 to 6 o’clock for short.
#3 - Say ATR is 50 pips and you are looking to go long. Add 50 pips to the current price for TP & subtract 50 pips from the entry price for SL.
#4 - sorry, don’t know how to post screen shots but pull up a chart, turn off Scroll & whatever the one to the right of the Scroll button is and then study charts - look for good crosses, hooks, how stochs look, etc. Study them. Good luck
