Spread Betting Trading System

need to know if I can build a trading system / strategy. Thank you

The difference between the purchase price and sales, called a difference is how the spread of paris made a profit. For example, if the current value of the FTSE IS 4524, then a spread of paris could quote a bid-ask spread of 4523/4525. Were you to buy £ 1 per point at 4525 you instantly record a current loss of £ 2, 4523 would be the price you could sell to. Therefore, for every change of 1 point in the quotation, your profit or loss vary from £ 1. See link below for a tutorial on the spread of paris on stocks.
