A Non-Trading EA Testing Indicators

All indicators can be divided into two groups: static indicators, the displaying of which, once shown, always remains the same in history and does not change with new incoming quotes, and dynamic indicators that display their status for the current moment only and are fully redrawn when a new price comes. The efficiency of a static indicator is directly visible on the chart. But how can we check whether a dynamic indicator works ok? This is the question the article is devoted to.
