Stock splitting! If my memory serves me correctly in my Vortex spreads I simply entered the new price. . say 50% of previous price and doubled the number of shares manually. . .total Value does not change and the PC remains the same as no buy is executed. Can't think of anything else right now than needs to be done. In the Vortex Windows program this works that same way. I will double check if I needed to do anything else. You can simply try it out and if it does not work exactly that way you can easily analyze where it goes wrong.
