Any trader who plans to earn income from currency exchange stories must consider the effect of prior expectancies on the market. This means making allowances for any movement that has already happened in anticipation of the statement. Imagine that the US GDP is getting ready to be announced. However, if everyone else expects the same thing, the greenback may already have risen in the hours and days before the announcement. Then perhaps, when the GDP is essentially announced, it turns out not to have gone up quite as much as folks predicted. So in that case, the greenback might actually fall. The news was still very good, but it did not reach the market’s expectancies. The choice to trading with the aim of making money from news press releases is, naturally, to stay out of the market any time a major announcement is due. Most traders who rely on technical research for their currency trading systems opt for this approach and it is highly recommended that noobs do this.
