DislikedWell depends on the options type and the player involved. A barrier or better a no touch option will force the owner (if its a large player) to protect the levels without breaching it while at the same time you have speculators trying to breach the level to kill the holders. You can have range plays, breakout plays, hedging plays, volatility plays, etc.
Others are for purely hedging purposes and those are a lot more difficult to evaluate, plus the price can be breached but as long the the expiration is above/below the strike without killing...Ignored
yea nice... i would add with the vanilla's it's not just delta hedging, so it's worth to maybe note them for the NY cut on days with not strong sentiment one way or the other, but hard to build a strategy just on that... but the barriers are great to use for targets in the trend.
let PA confirm them like you said, because once you break out of ranges you'll be hearing about barriers every 50-100 pips smaller every 25.
