Hi I am running a backtest and plotting the portfolio equity curves. I have noticed that when I shift from one share code to another, the cash value seems to vary widely. The equity curve looks similar and the drawdown is similar (final numbers all the same) but the Cash is very different. If I knew how to attach images to this post I would post them to show what I mean. I would have thought that since the portfolio equity reflects the portfolio situation, that changing the share code would not alter the cash situation but it appears to dramatically.
Has anyone noticed this happening or can offer an explanation about why is is so? All help gratefully appreciated. Cheers Shane
