Thanks for the information. About the chart. The NZSX50 Index chart is the value of the 50 largest companies on the NZ exchange. I guess this is number of shares times market price of shares somehow weighted to form the NZSX50. The top graph I am not sure about what is this. Is it the volume of shares being traded with 100 being the average daily transactions.

I would have thought volume would increase as the decline increases as everyone tries to sell out but I guess if its the value of the trades rather than the quantity of shares it would decline as prices plummet.

Where would you get charts like this from. Do you rely solely on technical analysis for your trading or do you also use fundamental analysis when choosing a company to invest in.
