Best Price Finder MT4
This script allows you to compare quotes and spreads from different trading servers or brokers to identify a server/broker that offers the best bid/ask price and the tightest spread.
It can be compared with up to six different servers or brokers at a time, and it is easy to find the best quote provider by score.
Usage: Open up to 6 MetaTrader client terminals, login to different servers/brokers, and then start the script on each terminal's charts.
