There are two types of spread when trading options which need to be considered when using an options broker: Options spread strategies – this is the name of an options strategy, the most common being straddles, strangles, condors and butterflies. Some of these can be traded online, but the majority need to be traded over the phone with a dealer. The better relationships your dealers have with market makers, the better the price of your spreads will be. OTC bid-offer spreads – unlike DMA options trading where you are charged a commission per lot, if you are trading OTC options via a CFD or spread bet, the commission will be built into the premium (also known as the bid-offer spread).
