Since the cost of the trade and the stamp duty is not specified the converter combines the trade cost and stamp duty into the trade cost field. Therefore the stamp duty field is always zero. This will not affect the capital gain calculation. In addition notice in the above screenshot how the trade cost is sometimes £4.90 or £5.10. This is because the share price has been rounded to 2 decimal points from 3 or more. The trade cost compensates for this discrepancy. Again this will not affect the capital gains calculation.
