Studies

Strategies

Each study states a published rule and shows that rule in code. The pages are for reading and for checking an implementation. They are not signals, and they do not rank a rule.

The sample is the ECB daily US dollar/euro reference rate from 2 January 2020 to 31 December 2024. Source: ECB statistics. It is one rate a day, not a broker price. Where a script runs, it states that series, the costs it assumes, and that past performance does not predict future results. It does not print a return.

MQL5 on these pages is illustrative. It was not compiled. Python and C# are run on the ECB file, and their signal digests are required to match.
