Forex pips indicators have a major speculative role to play in the foreign exchange market. They refer to the minute increments of a given currency. PIP is an acronym for “percentage in point” and forex rates are expressed up to 4 pips or 4 decimal places. In forex trading, they represent the smallest changes in the currency value. Even a small change in a pip can have a heavy effect on the final value of a particular currency upon its purchase or sale.
