Using 1 min time frame for entries on VX algo & day trading

what time frames do you use to confirm entries outside of a buy signal?

If I am day trading, I will mainly use the 1 minute time frame to look for moving average support and resistance, and read the candle stick patterns as well from that chart.
However, there are times I'll switch to a 5 minute and 10 minute time frame to take a look at levels for moving averages and see what the candle stick patterns are from there.
So for example, today we had 3 of the x1 sell signals around 9:31, so we pull up the 1 min chart, we are getting confirm break of the 1st moving average support = bearish confirmation #1, follow by DHC = Bearish confirmation #2 , and the sell signal is already 3 confirmations, so we need to short ASAP.
