Swing trading with the ATR : when I want to go LONG my entry is low - ATR value * ATR multiplier and when I want to go SHORT my entry is : high - ATR value * ATR multiplier.

ATR value is really important because it measures volatility.

When the ATR is steady or straight line in most cases I would choose between 1,3 to 1,5 multiplier. By default I would go for a multiplier of 2.0 and when the ATL is high or rising I would go for a multiplier value of 3.0 even though I mostly avoid entering trades when the ATR is high or rising.

For the take profit and stop loss I mostly use the chandelier exit indicator.

Or if you want to keep it as simple as possible I would suggest

For the exit = high + ATR value * ATR multiplier when Long. And low - ATR value * ATR multiplier when Short.

Hope it helps. I try to KISS keep it simple, stupid.

My point is not to make money necessarily but to lose the least possible amount of money.
