swing trade with good ROI

price is squeezing between two trendline.
Today is the breakout day but at end of day some sell off happened so if tomorrow or next any day there is a pop out candle of 2-3 % then we should take entry with stop loss around 3% or below today candle & target will be around 10-12%
A very good RR ratio trade 1;3
please intact with stop loss

how to do risk management with quantity?

quantity = risk per trade/stop loss(in rupees)
example-
let suppose you have 100000 capital.
if you want to risk 2000 rupees without any hole in your pocket then,
stop loss 10 rupees so
quantity =2000/10= 200 q
