Look like DDOS protection from exchange. Increase your rate limit would help in long terms

I got the same error from today, my bot is running for 6 days !
This Is a log exemple :
freqtrade.strategy.interface: WARNING - Empty candle (OHLCV) data for pair OMG/USDT
My rate limit is set to 300

Are you using docker or native install?
what does this output?
curl -s -D - "https://api.binance.com/api/v3/klines?symbol=BTCUSDT&interval=1h"

(.env) lvp@lvp-VirtualBox:~/freqtrade$ curl -s -D - "https://api.binance.com/api/v3/klines?symbol=BTCUSDT&interval=1h"

should I just go ahead and install this?

Had same issue here. Fixed by installing pandas-ta:

pip install pandas-ta

Yes. Also tell us if you're using docker or not.

not using docker, just native install.

I had similar issue. Might have found the reason.

Initial error, and this was for most if not all coins:
freqtrade.strategy.interface - WARNING - Unable to analyze candle (OHLCV) data for pair CELR/EUR: input_arrays parameter missing required data key: ema1

By suggestion from @topscoder I did "pip install pandas-ta".

Now log just mentioned one coin:
freqtrade.strategy.interface - WARNING - Unable to analyze candle (OHLCV) data for pair CELR/EUR: inputs are all NaN

I found out that on my exchange (Bitvavo) CELR was blocked from trading. So api-request must have reported NaN witch must have threw off the script. I blacklisted this coin and now it appears to be working.

pip install pandas-ta

didn't help! already had that library installed :(

[Gjuju]

Try with pandas_ta instead of pandas-ta

@LucianPopaLVP is this still a problem?
