In themean time - before you go out and buy a tool to make the data into the right format for you ( from : http://www.trading-tools.com/heikin-ashi-for-metastock.htm - I don't know anything about it, it might work, it might not etc, caveat emptor) ....
There is a way to exploit MS to create a sort of H-A plot...
The code:
xClose:=(O+H+L+C)/4;
xOpen:=(PREV+Ref(C,-1))/2;
xHigh:=Max(Max(H,xOpen),xClose);
xLow:=Min(Min(LOW,xOpen),xClose);
{plot}
xClose;
xOpen;
xHigh;
xLow;
Now we have to plot this in a very SPECIAL way.... it takes some fiddling around, but once you get right you can save the chart as a template and then you never have to fiddle with it any more!
First plot the indicator as is in a chart, overlayed over the base security.
Next click the line that is the xHigh, and format this as a histogram in whatever colour you like.
Now click the xLow and format this is a histogram in the SAME COLOUR as the chart background. This is now the high/low bar.
Click the line that will be xOpen and format this as the very last style in the line-style drop down box (the one below histogram), and make the colour whatever you like and the line-weight the heaviest, or the one just above the heaviest. It should look like a seris of coloured dots on your high low bar.
Do the same for the the xClose.
Now hide the underlying security by making it a line chart with the same colour as the background.
You now have something that should resemble your H-A chart. You might have to retrain your eyes and brain to 'see' the candles in this way, but you had to train it in the first place to see the candles, so this shouldn't be too strenuous.
Hope this helps.
