A spread monitoring Expert Advisor (EA) provides critical insights for traders dealing with varied broker spread rules, including fixed, ECN, and standard accounts. This tool is instrumental for those wishing to gauge spread fluctuations and optimize EA performance accordingly. It continuously tracks and records the minimum and maximum spread values per day, resetting at midnight based on the broker's terminal time.

For flexibility, users can toggle between pips and points in the settings and choose to sort instruments by the highest spread. The EA is assigned to a chart that isn't involved in real trading, displaying data for all instruments visible in the Market Watch. By utilizing a unique labeling system, it minimizes traditional comment formatting issues, allowing clean presentation without the influence of chart backgrounds or grids.
