Lets say you trade 15 minute candlesticks and they form at 1:10pm, 1:25pm, 1:40pm, 1:55pm, 2:10pm, etc, instead of the usual 1:00pm, 1:15pm, 1:30pm, 1:45pm. Do you think this would have an effect on your ability to read price action or be unsynchronized with the market? Would there be an edge in using odd timeframes that people usually don't study like 7mins, 18mins, 48mins?
I have always wondered about that, whether using infrequently used timeframe and/or with odd frequency would actually be able to allow you to see a pattern before others, i.e. a doji forming on a 10-min. chart before it actually appeared on a 15-min. chart? But then again, the opposite might also happen in that you might miss a pattern that showed up in 15-min. chart but just didn't materialize on the 10-min. chart.
I think the best way is backtest them. TOS does offer different timeframes in their charts that are different from the conventional ones so you might want to test it out to see if there is really any benefit in using unconventional timeframes.
