The dow mini or YM is very similar to the S&P 500. A couple of reasons why I prefer the dow:

The YM can be traded using a tighter stop than the S&P. My setups use a 10 points stop with the YM. When trading the ES, a 1pt stop is guaranteed to get stopped out.

The liquidity is thinner compared to the ES. This makes it alot easier to spot volume on the tape without risking any slippage.

There is also the psychological side when trading the YM. Greed plays a big factor in trading. Many new traders will refuse to take a 1-1.5 point profit in the ES just to see their stops get taken out. In the YM, a 15 point profit is alot easier to take than a 1.5pt profit in the ES.

When buying the test of the lows or shorting the test of the highs, the ES tends move 1+ point before reversing. This hurts alot of new traders using tight stops. In the YM, price will usually stay within 6-8 points.

Aggressive and experienced traders trade the S&P. For new traders, the YM is a good contract to begin with. Price does not move as rapid as the ES.

Market profile works really nice with the YM as well. This is probably the main reason why I trade it.
