there is no way that you could set a stop loss in altcoin markets, no matter in what kind of exchange are you trading,
Wrong! You can set it with Poloniex, Bittrex and yes, Kraken. But its very confusing in Kraken because theres a lot of order types.
zypa, the best way to do it on Kraken is to use
Stop Loss Limit and set the price where the sell order should acvtivate and then at what price you want to sell.
