David Fuller's view I had been raising my trailing stop on corn because it was becoming overextended in the short term, although not relative to its potential indicated by the large base. Nevertheless, base potential may or may not be fulfilled anytime soon and I hoped to be out before the first correction became obvious. Having raised my trailing stop again this morning, this was triggered this afternoon at $5.12 against my purchase at $4.289 on 12th August. These prices include spread-bet dealing costs.
