The ATR in $ terms for NQ is like 70% of what it is for ES, which is another way of saying NQ costs more than ES (due to higher margin requirents). The ATR in $ terms for YM is like 80% of what it is for ES. The ATR in $ terms for TF is like 200% of what it is for ES which makes TF a much lower cost contract to trade than ES - but with higher leverage comes higher risk of ruin. TF and CL are a scalpers dream to trade but they are so levered that there is very little room for error, they are for the real experts and I ain't there yet.
because you have one market maker in there keeping the spread 20 pips wide, who decides to overshoot or undershoot the spot market by 40 pips, or just decides not to move the market at all if they choose not to. lol
lower tick size widens the spread. you won't see algos going toe to toe stacking 1000+ fake orders over every dime (as if depth of market mattered anyways). Quarter ticks keep it tight, liquid and lets you get in with size which prevents a lot of horseshit like you see in less liquid markets. No reason to reinvent something that keeps the playing field even for all levels of players, large or small.
