Grain Futures Trading Journal
Corn, soybeans, and wheat don't move on the same clock as a financial futures contract -- their volatility is seasonal and report-driven rather than macro-driven, and the calendar itself (planting, growing season, harvest) shapes risk in a way that never applies to a gold or Treasury contract. A journal that treats every futures contract the same misses that.
The contract math across the grain complex
Corn (ZC) and wheat (ZW) both tick in quarter-cents (0.25), worth $12.50 per contract on a 5,000-bushel size. Soybeans (ZS) share the same tick structure. Fillbook logs every fill against each contract's real point value, so P&L and R-multiple reflect actual dollar risk, not a rounded guess from converting cents-per-bushel by hand.
USDA reports are the dominant scheduled-volatility event
The monthly WASDE report, weekly export sales data (Thursdays), and in-season Crop Progress reports (Mondays during the growing season) routinely move the entire grain complex within minutes of release -- a different, government-data-driven event calendar than the Fed-decision risk that dominates metals, rates, and equity-index contracts.
Seasonal, not macro-driven
Spring planting-weather uncertainty, summer growing-season weather risk, and fall harvest-pressure selling create a real seasonal volatility pattern layered on top of report-day risk -- a pattern with no equivalent in a financial futures contract that trades on the same rhythm all year.
Liquidity thins outside the front month
Grain futures liquidity concentrates more heavily in the front contract month than a financial future like ES or GC, so rollover timing has real consequences for fill quality. Logging which contract month each trade was actually in is what makes that pattern visible in your own results rather than assumed.
Frequently asked questions
Corn (ZC) and wheat (ZW) tick in quarter-cents (0.25), worth $12.50 per contract. Soybeans (ZS) use the same tick structure. Fillbook applies each contract's real point value automatically rather than requiring a manual cents-per-bushel conversion.
The monthly WASDE report, weekly export sales figures, and in-season Crop Progress reports all give the market new supply/demand data at scheduled times -- the market repricing to that new information is what produces the sharp, short-window moves, not random volatility.
Yes -- P&L, R-multiple, and position sizing are all calculated per contract using each contract's real point value, whether trades are imported via CSV or synced automatically from a supported platform.
