Thank you. I also monitored 3, 5 and 7 minute charts while trading. 3 is a good compromised..
FWIW, I found that my system didn't give very many entry signals per hour on 5 minute charts, and that 1 minute charts were a bit too fast.
Using 2 minute and 3 minute charts turned out to be the Goldilocks solution: not too fast and signals occurring in a timely manner.
You are a slope trader? I think there are a couple of others on ET who are also using slopes.
