GDAX Crypto Currency Exchange supports the following order types

• Market: Buy - Buy at best market price. Matches to the best available sell orders on the order book. Always a taker
• Market: Sell - Sell at best market price. Matches to the best available buy orders on the order book. Always a taker
• Limit: Buy - Buy at the Limit Price or below - The Limit Price is usually below ASK price. If the limit price is at or above the current ask price, then the order will execute immediately and is a taker, otherwise a maker
• Limit: Sell - Sell at the Limit Price or above - The Limit Price is usually above BID price. If the limit price is at or below the current bid price, then the order will execute immediately and is a taker, otherwise a maker
• Stop Limit: Sell - like a Stop Sell, but when triggered, it becomes a Limit Sell at the specified Limit Price (See Limit Sell above). Can be a maker or a taker depending on if the limit price is above the Bid price when triggered.
• Stop Limit: Buy - like a Stop Buy, but when triggered, it becomes a Limit Buy at the specified Limit Price (See Limit Buy above). Can be a maker or a taker depending on if the limit price is below the Ask price when triggered.

NOTE: "Taker" orders incur 0.25% fee. "Maker" orders are free

NOTE: Stop Limit orders are only available on the GDAX Website. Their API does not currently support them, so we cannot make them available in Medved Trader

POST ONLY: LIMIT BUY and SELL orders can be specified as "Post Only", which means that the order will only be accepted if it is a maker, and will be rejected otherwise. In Medved Trader, Post Only is a "Special Instructions" option on the order and is available in the dropdown list on the trade ticket, or right click menu on chart and DOM window order capsules
