In index futures does this subject get the attention it deserves?How is position size handled? Is it all in at the entry trade? Should you instead at entry scale in? In YM I enter the trade always with ammunition to scale. If if whips off in the predicted direction without a counter move, I eventually take profit on my original entry position? If there is a countermove first, I will enter again at a calculated spot below my buy entry or above my sell entry. If it is YM or ES or another e-mini, how do you position size? I'm not asking what are the actual number of lots you do because that may be part of your system. What is the ratio? Do you do your position size only at entry? Do you spread your position size at entry? If you buy do you add by scaling up or down depending how price initially moves? When exiting do you scale out or do you take all out on target move achieved?
