There has been a lot of rumblings about the poor trade matching engine on Kraken in the past few months, with one day bringing some cryptos down 90% for only brief moments, ETH down to 700$ for a moment while it traded at 1400 on other exchanges. Kraken is one of a few US exchanges that offer high leverage, high being up to 5x. There are some serious flaws in their system seems to me they base SLs and Liquidations on internal exchange prices rather than aggregate of other exchanges. I think I will come back and write more on this idea. There is a lot to research but I am pointing out on BTC the one crypto with the Largest liquidity pool 4-6% wicks occurs not too infrequently. Ill stick to Kucoin for now, no thanks.
