But sometimes the swap is shown as zero
and the profit shown is directly sell minus buy. In the image shown below, check the last entry ... "Sold 2 lots @1.3161 and bought back at 1.3158. Profit = 60".
But first things first.. what exactly is a spread and a swap and how does it contribute to the trading costs and profits ?? I think the spread is the difference between bid and ask, but how does this thing work ??
