With regard to Stock Exchange Date for the ASX, can I ask how far back your price history data goes and how accurate it is?
The reason I ask is that I have purchased my data from JustData (inc history) and apparently the Price history is supposed to date back to 1981.
However, looking at the individual price charts the data does not seem to really go back beyond 1998. In additional there seems to be more holes in it than in a swiss cheese!!!!
As my experience of the Australian Markets is limited can I ask whether this is the norm?
The reason I ask is that I am keen to backtest some strategies but it seems clear that the data I have for the Australian Market is unsuitable.
Any advice most welcome,
