its not a bias. You should expect that because it is the risk/reward the market is giving you.. You can try to buy/sell delta 10 put or call spreads any time and they will be priced close to the numbers i gave..
There is a big difference between directional as delta neural positions imply you do not have a bias or opinion other than is the theta enough to harvest over the next few weeks given the hedges/adjustments you might need to make.. and any adjustments are done almost mechanically on deltas or p&l or %
For the im in profit in my long so wont move my stops — i think you mean the one side is under pressure and the other isnt. you can kind of tell if you should move or do something else by the premium left in the profitable side. If there is not much left then it wont hedge much and maybe you should do something that entails considering the worthless side.
