For news impact trading, put all the money you got in the port and open maximum allowable contract size
1 contract size requires $3,850
EP to SL = 1.4 tick = -$140
Commission fee = -$30 (per 2 times position)
EP to TP = 9.4 tick = +$940
Risk/Reward Ratio = 5.529
%ROI = 940/3850 = 24.41%
I have $50,000 in port
Maximum allowable contract size = 50,000/3,850 = 12.98 = 12 contracts
I will gain $940 * 12 = $11,280
I will lose -$170 * 12 = -$2,040
