CBOT Trends-Wheat down 17-20 cents, corn down 4-7, soybeans down 1-4

CHICAGO, April 8 (Reuters) - The following are U.S. expectations for the resumption of grain and soy complex trading at the Chicago Board of Trade at 8:30 a.m. CDT (1330 GMT) on Wednesday:

WHEAT - Down 17 to 20 cents per bushel

• Wheat sharply lower as tumbling crude oil prices triggered long liquidation and technical selling. Forecasts for crop-boosting rains in parts of the Plains wheat belt added further pressure.

• Benchmark CBOT May wheat WK26 fell to its lowest level since March 5 during overnight trading, but held technical chart support at its 50-day moving average.

• Rainfall forecast through the weekend is expected to recharge dry soils in the eastern areas of the southern Plains wheat belt. However, western areas of the region could miss key rains, meteorologists said.

• The U.S. Department of Agriculture is due to release its monthly crop supply and demand report on Thursday. Analysts polled by Reuters, on average, expect the report to show a slight drop in U.S. ending stocks and a minimal increase in global supplies.

• CBOT May soft red winter wheat WK26 was last down 19 cents at $5.79 per bushel. K.C. May hard red winter wheat KWK26 was last down 16-1/2 cents at $5.91 per bushel, and Minneapolis May spring wheat MWEK26 was 13-1/2 cents lower at $6.27-1/2 per bushel.

CORN - Down 4 to 7 cents

• Corn futures down as sharply lower crude oil prices sparked long liquidation and technical selling.

• Actively traded May corn CK26 broke through technical chart support at its 50-, 100- and 200-day moving averages during overnight trading and reached the lowest point since March 4.

• Traders are squaring positions ahead of Thursday's USDA crop supply and demand report. Analysts polled by Reuters, on average, expect the report to show slightly larger global corn ending stocks than the USDA's March forecast and slightly bigger harvests in Brazil and Argentina.

• CBOT May corn CK26 was last down 5 cents at $4.44 per bushel.

SOYBEANS -Down 1 to 4 cents

• Soybeans lower as falling crude oil dragged down soyoil prices.

• Actively traded May soybeans SK26 broke out of a recent narrow range and fell to the lowest level since February 20. The contract broke through technical support at its 50-day moving average.

• Traders are squaring positions ahead of Thursday's USDA report. Analysts polled by Reuters, on average, expect the report to show slightly larger U.S. soybean ending stocks and a smaller harvest in Brazil.

• CBOT May soybeans SK26 were last down 1-1/2 cents at $11.56-3/4 per bushel.
