If you are a trader of LINE be sure to watch LNCO and BRY on the same chart -particularly the volume. There are traders that are selling one while buying the other to 'paint the tape'. When the bid volume is low they will sell that security and buy the other equivalent in the hope that the lower price they created will scare holders out of their positions. The opportunity is to do the opposite and ride the wave they create. You don't need high speed, just L2 and all three tickers. Just keep your bid and ask ahead of theirs when you see say LNCO spike up and LINE spike down.
As always HOLD LONGS IN A 'CASH' account to keep them from being loaned.
navkram: That is exactly what is happening... LNCO/LINE/BRY are trading in reciprocal waves - run on uptick, then sell, then run to the other and do the same - (the old wash, rinse, repeat cycle) - note that today is a triple witching from yesterday too, plus day-traders who bought LINE @ low 30's are cashing in their profits on the highs; LINE is trading within a limited band width of $1.00 up/down - should be a wild ride - also, of bigger import is that this market correction is not over yet and liquidity issues are rising in re hedgefunds who are short and must sell-off stock to cover... Please use caution...
