An order in which you specify a stop trigger price to activate an open market order to either buy or sell a cryptocoin.

Example: 

-Lets say you have 5 (LTC) which is currently trading at $10,000.00 pesos per coin. 

-You place a sell stop market order with a stop price of $9,500.00 pesos. 

-If the stock price falls to $9,500.00 pesos or lower.

-Then it will activate a market order to sell the coin at the market price.
