      A number of different tools can be used to determine whether or not astock might run for a strike price (also known as "running for the money").The first and easiest way is to scan through a list of stocks that havelarge outstanding interests in the underlying options contracts. (Some prep-work is required for this strategy.) Keep a close eye on your list ofstocks, and scan them throughout the day. When you have identified a stockthat could be a runner, look to the inside quote. You will often see largesize at the bid or offer. Traders attempting to move the market to aparticular strike price will show their muscle. By showing size at theinside quote, traders using this strategy hope to 1) scare off anyonethinking about going the other way, and 2) seek assistance from othertraders looking to make a fast buck. By showing size, traders thinkingabout selling may hold off until the buying subsides, and vice versa. ForDay Traders, size at the inside quote is a strong indication that the stockis going to move in a particular direction (as long as there is limitedresistance on the other side of the inside quote). For over the countersecurities, traders have the advantage of seeing which market makers arebidding for and offering stock. If one particular market maker is showingsize and/ or taking the offer and upticking the bid continuously, you canbe quite confident of the reason behind his actions.
