All trading actions can be done in the Trading Dashboard. The panel where you can place orders is by default on the bottom left, named Order Entry.
The trailing stop order is a bit more complicated to put in context. Here, we have already bought 0.01 ETH at 0.12497 BTC (see How to place a market order). Now let's say we want to sell it back for profits. We can always set a limit price higher than 0.05201 BTC, for example 0.07, but what if price rises higher than that? A solution here is to set a limit that trails after market bid. If price rises to 0.07, your limit trails after it, and you don't miss out the profit. If price falls and hits the limit, order gets executed, and whatever profits you may have from the rise before is kept.
If you are buying with trailing stop, the limit will trail "before" market ask. See Stop order.
With that in mind, let's place a trailing stop order with a trailing amount of 0.015. Fill out all required fields:
- Price distance: trailing amount, i.e. how much you want the limit price to trail after market price.
- Distance type: you can choose between "fiat" (actual number) or percent. For example, if market price is 0.06, a 0.015 price distance means limit will either be 0.045 or 0.075.
- Quantity: how much you want to buy or sell

Your trailing stop order has been placed and is now displayed in the Orders tab.
How does it work from now?
Essentially, it is a sell stop order for 0.01 ETH with stop price 0.015 away from 0.05201, which is 0.03701 BTC. If market bid moves up to 0.06, new stop price is 0.045. If market bid moves further up to 0.1, new stop price is 0.085. At any point, you can cancel the order and then place a market order immediately after to sell at a good price.
On the other hand, if market bid moves down from 0.1 to 0.09, stop price stays at 0.085. If market bid moves further down to 0.088, stop price still stays at 0.085. Once market bid hits 0.085, the trailing stop order is executed. Note that the average price in the end can be different than stop price due to slippage.
