Quote from NoDoji:
Being a lady, I tend to trade the underlying and I prefer an instrument with a decent tick size, you know. Once positioned, if there's a sign that the guy on the other side is about to pull out, I make an offer he can't refuse.
The problem with decent tick size is when the other side is massively long and the gyrations get too large, then its hard to stay committed. When your sizing is bigger than normal its especially important to get the entry point right.
In any event, I would always advice a beginner not to oversize an outright naked position, ideally use some kind of protection.
