As a day trader, I use a timeframe where I can see the end of the last day and the morning of the trading day on the chart. I only trade mornings (Eurex, then US). So on the Bund, it's about 3-400 on the ES about 7-800 (ticks).
If I went too low, I wouldn't really have any clue what the bigger picture was. If I went too high, I wouldn't see the major intraday moves. within the extremes, doesn't matter.
So a swing trader using a yearly chart would probably be screwed but a daily vs a 4 hour - can't see how it would matter,
