FOR SCALPERS, how many percent is the minimum target gain per trade FIRST WITHOUT THE LEVERAGE?

so as the title says, for scalpers here

how many percent is your minimum target gain per trade WITHOUT THE LEVERAGE in the calculation?

i want to know this so that i could plot it in my chart on trading view of an estimate on how my long position should look like

since as of now i just aim for a minimum of 1:1.5 or 1:2 risk to reward ratio but the gain percentage varies since it depends on where i put my stoploss

thanks
