You can suggest anything that you think has greatest day range or trends in one day but it has to follow some rules 1. High liquidity 2. Most of the time moves one tick in price (in other word i don't want some crazy 500$ stock that jumps around)
I love trading the Russell 2000 future ER2 never had a problem getting in or out and it jumps all over the place. Tax advantages to trading futures too..
EUR futures are plenty volatile enough for the depth of market offerred, spread is one tick for most of the day. If it don't move fast enough for you, just turn up your size You will likely be paying 5+ticks/round trip on the thinner currencies.
HSI, DAX, ER2 all offer consistent volatility and liquidity. you can play stuff like ZB, ZN, and so forth on big report days (i.e. FOMC) and get some pretty heavy movements as well. hth take care omni
