To my mind it's almost impossible to find such chart, you know. I'm sure there are no one second charts at all. I guess, that if there wer such charts it would be very difficult to trade on them ebcause you must have a reaction and speed which let you to trade and make profits on one second chart. I'm convinced that its useless for many traders, they would better choose another chart like a minute chart and train there because the vast majority of traders don't want to complicate their trading activity hence they'd be happy with the chart which they chose. Comfort also is a part of trading, there is no trasing without comfortable conditions.
