This paper characterizes the trading strategy of a large high frequency trader (HFT). The HFT incurs a loss on its inventory but earns a profit on the bid–ask spread. Sharpe ratio calculations show that performance is very sensitive to cost of capital assumptions. The HFT employs a cross-market strategy as half of its trades materialize on the incumbent market and the Ugg Cheap Uk Store
other half on a small, high-growth entrant market. Its trade participation rate in these markets is 8.1% and 64.4%, respectively. In both markets, four out of five of its trades are passive i.e., its price quote was consumed by others.
We have reviewed a series of 203 patients who underwent retrograde cardiac catheterization by means of brachial arteriotomy. Occlusion or stenosis Ugg Gloves Stockists Uk
of the brachial artery (BA) associated with unobtainable auscultatory blood pressure (BP) occurred in 57 patients (28 per cent). Of these 57 patients, 8 (3.9 per cent of the total series) had no radial pulse. Brachial arteriotomy has become a major cause of absence and inequality of BP and radial pulses. Failure to appreciate this fact may lead to dangerous errors in diagnosis and therapy, particularly in shock.
