Recommendations:
This multicurrency event handler is resource-intensive. Adjusting the delay variable in the script can reduce CPU usage but may result in skipped ticks. After launching the script and Expert Advisor, you can add or remove symbols in the "Market Watch" window as needed. The code is customizable; for instance, you can modify it to capture the Ask price instead of the spread.
