# Calculated EMAs very different from displayed

I’m calculating EMAs 20, 50, and 100 for 1m candles using python TA-Lib on the futures testnet. And I see the calculated values off by a big margin from the displayed ones. Any idea why that is?

Hey,
It seems the issue might be related to the non-official Binance library you’re using. I recommend reaching out to the library’s community for assistance or considering the official Binance library to check for any differences.

You mean TA-Lib? No, that’s not the problem. I’ve written this code using simply pandas and the issue is the same.

I meant the following library: python-binance · PyPI
