No it is not an actual stock with a ticker symbol. It is called BTC CFD (contract for difference) and is artificially created by my broker (this is why it is an over the counter deal), but it stays very close to the price action of real BTC. The moves and waves are exactly the same. The highest difference I have encountered was 5$. If I trade 3 CFD, I win or loose 3$ for every 1$ real BTC moves... I can scale it from 0.1CFD to 50CFD. Never traded more than 3CFD though, because of huge risks. I can put an exact stop level, where it ends the trade unless there is an overnight gap. Just pure awesomeness with this kind of vola in BTC... and the spreads are very low !
