No I've never heard of Dunnigan. Maybe I should look him up. In terms of timeframes, I would encourage anyone trying this for themselves to ONLY work with 5 min chart and adhere strictly to the criteria I listed on Page One. It's the old LESS IS MORE principle. With smaller timeframes the first rule that gets broken is the number of trades per day, which should only ever be one per time period.
Not to say that some people can't incorporate other stuff if they really want to, and have experience. But my personal experience in finessing things via smaller time zones is that I just outmanoevre myself. I end up missing my target too much, taking smaller profits and overtrading. I start getting too clever for my own damned good. Sometimes it's better just to learn to sweat things out in the 5 min timeframe.
I also don't believe you can do effectrive intermarket analysis between the 4 symbols in anything other than a single timeframe. So if you are trading the ES on a 5 min chart and also using it's 1 or 2 minute chart, then I guarantee you are not paying close enough attention to the DAX, ESTX50 and YM 5 min charts. And in my mind, it is the other 5 minute charts that will keep you on the straight and narrow!
