At the suggestion of studentofthemarkets, I am looking into the possibility of trading futures via AMP. To get an idea of what's what, I bought the E-mini Dow at 34,418 and sold it at 34,422.
For the purpose of this analysis, I am calling the digit all the way to the right a unit. Since my Profit was $25.00, it would appear that each unit is worth 25 ÷ (34,422 - 34,418) = 25 ÷ 4 = $6.25.
In my book, $25 for 30 seconds of activity isn't all that bad. But trading in this manner would mean I would have to time all my entries just about perfectly, at least in the beginning. Because if I were to give myself just 10 units of breathing room and ended up getting stopped out of the position, I would incur a loss of $62.50.
For some reason, when I tried to buy the E-mini S&P 500, the platform kept telling me that I was entering an invalid stop loss or take-profit target...
I bought the E-mini NASDAQ at 14,645.75 and sold it at 14,647.00... a difference of 1.25.
So, given that my Profit was once again $25, if I consider the digit preceding the decimal point to be one unit, each unit is worth 25 ÷ 1.25 = 20. Again, this will demand near perfection, because a stop loss of just five units would cost me $100 if it were hit.
Unfortunately, I will have to wait before analyzing the E-mini Russel given that this index is bearish, meaning I'm going to have to let it climb first, and then start coming back down in order for me to maximize the probability of my entering a profitable short position.
