It's happened three times now on Kraken that the price will be stable in a $50 range for 2 hours and as soon as I fill an order then within 1 minute the price jumps $400 in the opposite direction. I've also tried layering my orders with stop losses and re-entries in three to four stacks. When I do this, the price on Kraken sometimes jumps instantly by $80 up to just below my final re-entry. This could be coincidence, but when there is zero price action on other major exchanges it becomes a ~2% probability of coincidence. And lastly, the reason I am sad is that whenever your margin trading equity for leveraged positions falls below 80% Kraken can liquidate you, and if it falls below 40% then they automatically liquidate you for up to 80% of your open positions. I think there is a conflict of interest because I have noticed that most of the time I get liquidated it is at the top or bottom of price action. This could be due to bots using margin analysis after the fact, but the liquidation level jumps every time the market changes from bearish to bullish. It's been twice that I've had a position drop to 50% equity refilled the equity only for it to liquidate at 60% or 80% equity, and when I do get liquidated, I get liquidated to 125% or 178% equity, despite customer support stating they only liquidate to get you to 100% equity. And when I say a $400 price change in 1 minute, I mean violent price action within 1 minute of my entry, taking place over several minutes with no scalping.
You can't make money trading just one single pair. Someone with dozens of millions' networth asked why Kraken has so many market makers, defining market makers as "market manipulators". It is because the bots can see all of your hidden orders before they get placed on the order books, and when Kraken wants to take profits they liquidate everyone's positions by up to 80% of their entry in order to bring them up to 100% equity (a.k.a. 178% equity)!
That said, it's my fault for underestimating the capabilities of hedge funds and bots... I should've hedged against euro or something. Just a bit bitter that I've lost my life savings, but perhaps my experiences can illuminate some traders. There's a miniscule chance that everything that's happened to me is coincidental. I'll let you calculate the odds.
