Thanks - that makes sense. The reason I am altering PointValue is because I am Spread Betting on the Forex. The formula for spreadbetting works as follows:
PositionSize = MarginDeposit = 1; NumContracts = 1; TickSize = 0.0001; Stop loss is 50 points away from entry point I risk 10% of my capital per trade: 10% * £20,000 is £2000 Thus PointValue = £2000 / 50 = £40 per point: ie. I bet £40 per $0.0001 of FX movement I assume this is a correct way of implementing it in Amibroker? Alex
