Money Flow Index (MFI) indicator results are wrong than expected #23

Closed dirname closed 3 years ago

dirname commented 3 years ago

Hello,

I cloned this repository according to the tutorial and tried to run the demo, but after I can see the chart display, I tried to use the MFI indicator, but the result was not what I expected. The value of MFI is fixed at 100. When I check the preview website provided by TradingView, this issue also exists.

Please help me as much as possible to solve this problem, thanks in advance :smiley:

This is a volume based indicator. You don't have volume.

Thanks, I mistakenly provided complete market data for the default chart. Now I added a volume field in getBars, and I got the expected result. In the future, can you also provide the volume in the default chart?

If you open https://charting-library.tradingview.com/ (not tutorial) you can see the volume there. In the tutorial we rely on the datafeed thus if datafeed doesn't provide volume, we can't generate it ourselves.
