"The ES moves in "handles", and "ticks". There are 4 ticks to a handle. The YM moves in Dow "points". Each point is a tick. The spread on the YM and ES is typically "one tick".
When discussing the ES, competent folks use the term 'ticks' ...when using the term "points" with the ES, it is highly likely to lead to confusion. "handles" and "ticks" when discussing the ES eliminates **all** possibilities of confusion; If the internet is down and you call your broker to move, cancel or place a stop/adjust a bracket; and insist on using "points" instead of ticks and handles, all bets are "off".
