In certain markets and at certain times, by using the average monthly range to choose options
strikes, we may find that the implied volatility has pushed the option premiums to unreasonable levels. This causes smaller traders to buy strikes that are too far out of the money, simply because they want to be in a given market and have limited capital.
In these cases, the use of the average monthly range should be telling you to either avoid that market, or to use a strategy that can get you closer to the current market price, such as a
debit spread (bull call spread or bear put spread).
