Market high and low price is on the date.

* (if shown) = market close price used not a projected price. This is used when we do not have market data available to calculate a projection

The likely trade price/value is our estimate on the likely price the trade took place at and is not the actual trade price. The likely LOSS/GAIN is our estimate. Where a profit/loss value is shown in the Likely Trade Value column, this is derived from matching trades between periods eg the most recent previous BUY is matched with the SELL for the same number of shares and the difference between the likely BUY price and likely SELL price is calculated. Where a profit or loss is shown in the Average Price of Previous Trades column, this is dervied using the likely trade price compared to the average of previous trades based on adjusted close
