I'm not sure if this is appropriate for this forum but just in case can anyone recommend a good data provider to use with lightstreamer?

I've so far researched these providers

Alpha Vantage

DX Feed

Xignite

Intrinio

IEX Cloud

Polygon.io

Market Stack

Tradier

QuantHouse

FIS

Quandl

Tradermade

FXCM

Barchart

Finnhub

Finage

I would like to create an informational website listing these instruments:
Spot indices – based on cfds
us-30-futures
us-spx-500-futures
nq-100-futures
u.s.-10-year-bond-yield
germany-30-futures
spain-35-components
ise-100
Spot commodities – based on cfds
carbon-emissions
gold
silver
btc-usd
bitcoin-futures
brent-oil
crude-oil
natural-gas
Currencies
us-dollar-index
eur-usd
usd-jpy
usd-krw
usd-try
gbp-usd
gau-try
usd-brl
usd-ils
usd-rub
Stocks

nio-inc
amazon-com-inc
apple-computer-inc
moderna
microsoft-corp
nvidia-corp
pfizer

alibaba
Also if possible SDGs and Impact indices
FTSE Russell’s Environmental Opportunities index
Bloomberg Barclays MSCI Global Green Bond Index
MSCI ACWI Sustainable Impact Index
iShares MSCI Global Impact ETF
Most importantly we need indices and commodities to be CFDs.
Any help would be very appreciated

Just hop to this post and think to get you another site add to your list.

If you're just doing research, I'd recommend starting out with daily data from financialmodelingprep and working up from that. FMP also offers intraday data for cheap. Other than that, they offer free 250 request /day.

And how do you check that the data from this site is really reliable?
