Nice idea for scalping the indexes, but there is one thing i don´t understand yet. Lets say at 7/25 ,2:42 PM the spread was 80. This doesn´t mean imho that i get +80 ym points for profit as i have to deduct the loss/profit from the other contract i buy/short from it. Lets assume at 2:42 PM i shorted es at 994.75 (closing value of 13 min chart) and bought ym at 9226.Then at 4 PM u cover es at 997 and sell ym at 9255. Profit calc. would be: es -2.25 ym +29 =-112.5+145 > net profit (without commissions) : 32.5$ One of the contracts always go against you (whether if u sell the spread or buy it). Greetings, Ingo
