1st post and Dumb question: does anyone out there know what the largest lot size per trade can be accepted through the eCBOT system for the mini dow? Just curious. I switched from ES to YM recently and really like it, not as jumpy and spikey and seems to work better for the system I'm using. Incidentally, I remember reading somewhere that the limit for ES on Globex per trade is 250 lots, and they were going to change it to 400 soon, or already have. I've seen plenty of 250 lot trades fly by in the T&S window for ES, but only have seen up to 20 per trade for the YM. Thanks guys.
