Should we include pre-market candles in the 9/20 EMA?

For 9 and 20 EMA calculation, should we include the pre-market candles? This could impact where the lines print in the first 10-20 minutes which could impact trading decisions.

 

I used to Swing stocks based on D1, 9sma and 21ema pretty close, daily worked fine, premarket is generally too low volume to be worthwhile.

 

I'm referring to 9/20 or 9/21 EMA on intraday candles, either 1 minute or 5 minutes. I'm not sure whether to include pre-market candles in the calculation.

 

I include it for VWAP as well
