Does anyone know how to get a VWAP indicator to work in a python algo?
Below is the only way I've tried that doesn't give an error. This also never seems to have a value other than 0.0, and it is never marked as IsReady. Any ideas what I'm doing wrong?
For the symbol, I'm pulling tick data (forex), and I'm also consolidating the data into hourly bars.
Thanks in advance!

The VWAP indicator should be updated with the TradeBar. For forex symbol, the available bar data is the QuoteBar. The only way to construct the VWAP indicator is updating the indicator with manually constructed TradeBar data. The TradeBar can be constructed with
TradeBar( DateTime time, Symbol symbol, decimal open, decimal high, decimal low, decimal close,decimal volume)However, for forex symbol, there is no volume data but the calculation formula of VWAP indicator needs Volume data. Therefore, all the volume would be zero and the VWAP indicator will be zero for the whole backtest. (For the attached example, if assume the volume has value like 100, the indicator value won't be zero). We don't have forex volume at this time.
