In the initial article, an Expert Advisor (EA) was developed with two trading strategy instances. This increased to nine instances in the second article and 32 in the third. Testing times remained manageable. A shorter single test pass is preferred, but overall optimization should still be completed within hours, not days. A single pass should finish in seconds or minutes for combined instances. Multiple strategy instances increase optimization time.

For the experiment, a new EA based on the existing OptGroupExpert.mq5 was created with necessary code changes and saved as BenchmarkInstancesExpert.mq5. Runs were conducted in different tick simulation modes, doubling instances from 8 to 16,384. Memory usage and simulation times were analyzed. Results indicated reasonable memory consumption and simulation times, with the highest number of instances...
