I want to warn you not to fall into the trap I did.
I was trading bets on a horse race. I decided to trade in a profit on a £100 bet. I clicked the trade profit button just as the race was about to begin. Instead of showing me a profit of £17 it showed a loss of £274. Horrifed I checked the Price and Volume chart to see that there was a spike where the odds had gone out from around 2.00 to 4.9 and that was what it had got layed at. To make things even worse the horse romped home to win
