I wonder what tick chart settings people using to trade QQQQ and SPY? Currently I use 233-tick for short-term window and use 613 for long-term but results are mixed. I appreciate you sharing. Thanks!

Unfortunately like many others after the first dozen pages or so it disintegrates into the equivalent of kindergarten characters standing around at recess arguing over who has the biggest pee pee. There are probably others. You may be interested in the "search" function in the top right hand corner of the page. It actually works pretty well.
TL, Funny, I actually remember seeing that thread but could not find it...maybe because tick was mispelled. Reading through that thread still deost not quuite help with tick settings for QQQQ, SPY
