Options question for advanced traders?
I've come across this puzzling activity: On a website I use for active options volume I came across this

My question is (both stocks are calls) why would there be such heavy volume for calls at the strike which is below what the current stock is trading? On the options chain the other higher strike prices are no where near as much volume. Why would traders prefer to buy the lower strike on a call volume??

There is no way to know why another trader made a particular trade.

There is no way of telling if the trader(s) initiating the transaction(s) were buying or selling. Assuming the other side of the trade was market maker, the market maker would fill the order whether it was a buy order or a sell order, assuming the price was right.
Even if we assume it was a buy order there could be any number of reasons, including:
o It was a "buy to close" order to cover a short position already in place.
o The buyer wanted to hedge a delta negative position and chose the lower strike because it had a higher delta.
o If it was a speculative buy, and the buyer wanted a higher probability of a profit and was willing to sacrifice some potential gain if the stock moves up more sharply than he expects.
Large option trades are usually part of a spread, so it is quite dangerous to use speculation on the reason for a trade as a factor in deciding. what trade you want to make.
