Kraken short

With the power of Kraken’s advanced trading engine, you can use extensions of margin from Kraken to buy (go “long”) or sell (go “short”) a variety of cryptocurrencies with up to 5x leverage.

You cannot have both long and short positions on margin open at the same time in a single currency pair . All long spot positions on margin must be closed before a short spot position on margin can be opened (and vice versa). See Flipping Positions.

To settle an open “short BTC” BTC/EUR spot position on margin, you must transfer to Kraken the amount of BTC you sold on the market for EUR when you opened the position . This satisfies your obligation to return to Kraken the BTC that Kraken extended to you when you opened the position (i.e., sold the BTC for EUR).
