Comparing to indexes, agricultural commodity markets tend to be less volatile, speaking intraday, and less noisy which means that grain markets lack those false moves that are present at the stock market and once intraday trend established it would keep direction in most of the cases. Another distinction would be the limit moves - as the grain markets are also food markets there is a certain regulation that prevents large moves outside pre-specified interval. This could be considered as some regulatory stop-loss price above or below which during a day session the price won't be allowed to move further. In grain markets, we have corn, wheat and soybeans. The limit for the corn is 30 cents, for the wheat is 45 and for the soybeans - 70 cents from the settlement price of the previous trading day. From here we see that the the volatility and volumes could be placed in the same sequence - the corn is less volatile, the soybeans tend to be most volatile while the wheat is in-between.
Okay, now some specifications. The grains are being traded at CBOT and the pit trading hours are from 9:30 a.m. to 1:15 p.m. central time while the electronic trading hours are from 6:32 p.m. to 6:00 a.m. The volumes and all the action is at pit session so for day trading it is recommended to trade during the pit session. Another interesting and appealing thing is that the day trading session is much shorter than other markets'. Personally, it appeals to me quite a lot as I have some time for preparing for the trading day before open as well as once market close there is also time to evaluate your trades, go through the passed session and start preparing for the next day.
The grains are quoted in cents, one quarter cent move in AGs equals to $12.50 or one cent move - $50. It's very similar to ES-minis. The symbols would be - ZC for corn, ZW for wheat and ZS for soybeans. The futures trading months would be as follows:
-Corn: Jul, Sep, Dec, Mar, May
-Wheat: Jul, Sep, Dec, Mar, May
-Soybeans: Jul, Aug, Sep, Nov, Jan, Mar, May
The futures expire on the 15th of the trading month. Today is March 15th which means that March 2015 futures have already expired. Generally, we trade the front month.
To sum it up, AG grain futures market is very appealing and interesting market that too can be day traded. The trading session is shorter while the AGs tend to trend without significant and unnecessary noise. I am in the very beginning of grain futures universe and I plan to go deeper in some day trading set-ups next as well as read and study more on fundamentals that drive AG markets.
