Started a demo account and currently spreading currencies. The spread chart is AD4Z:AD5H (1:-1) on a 60 min time frame. I contacted the broker because the price seems to be based on the last making it appear that the spread is profitable, however, the market can be 10 points away giving an inaccurate open trade equity. Is this a standard or normal way for spreads to be based off the last and not the bid? It says that I have made $1,240 this week minus commissions and I have a hard time believing this. Please advise.
