I trade all the major European exchanges and none of this US bullshit happens there! Not in Paris. Not in London. Not on Xetra. Not in Madrid. Not in Milan. Not on Chi-X. Not on OMX. Not in Oslo. Yes, they're all electronic. They just don't have these leeches like in the US fucking up the market every day!
Utter rubbish - European markets have had giant intraday swings on fat fingers, options expiry, 9/11 liquidity collapse etc.
100% agreed. The market rules for when to bust things have been on the books for a long time but I totally agree. If you can stop your fucking algo then, well, that's the cost of doing business. Tweak it for next time.
