Does MT5 have more built-in chart options?

The official comparison lists 21 versus nine timeframes and 38 versus 30 indicators. More options are not evidence of more profitable signals.

Does only MQL5 support classes?

No. MQL4 also supports object-oriented programming. The APIs and program artifacts still differ.

Can MT5 load an EX4 EA?

No. Adapt available source and dependencies to MQL5 and compile EX5 output, then validate behavior.

Is OrderSend only for pending orders in MQL5?

No. Its request action also supports market deals and other trade operations. Check result codes and execution events.

Is MT5 automatically faster on every test?

No fixed runtime advantage is established here. Parallel optimization capacity and single-pass elapsed time are different questions.

Should I switch platforms?

Base the decision on the actual broker account, required features, dependencies, and adaptation/validation effort. No universal recommendation is made here.

MT4 vs MT5: Evaluate a Migration to MQL5

MT4 and MT5 are separate trading platforms. MT5 adds multi-symbol testing and other analysis capabilities, but migrating an existing MT4 workflow requires checking account availability, dependencies, and program behavior.

Key Takeaways

MetaQuotes lists 21 timeframes and 38 indicators for MT5 versus 9 and 30 for MT4.
More chart options do not establish better predictions.
Both languages support object-oriented programming; their trading and indicator APIs differ.
MT5 parallel optimization and forward evaluation are capabilities, not a fixed speed or accuracy guarantee.

Compare documented chart capabilities

The official comparison lists 21 MT5 timeframes, 38 indicators, and six pending-order types versus nine timeframes, 30 indicators, and four pending-order types for MT4. These are platform features, not limits on how many indicators may be attached to one chart. MT4 also documents a Depth of Market interface; the data and controls should be checked for the actual broker and symbol.

Inventory source and compiled dependencies

MT4 uses MQ4/EX4 and MT5 uses MQ5/EX5. An EX4 file is not a native MT5 program. Some calculations can be reused from available source, but trade handling, indicator interfaces, and dependencies need adaptation. Both MQL4 and MQL5 support classes and inheritance. A conversion should preserve intended timing and state, not merely replace function names.

Understand the MQL5 trade interface

MQL5 OrderSend sends a trade request whose action can describe a market deal or another operation, including a pending order. PositionOpen is a CTrade library method, not a mandatory separate language-level alternative for every market order. Both return values and server result codes require inspection; a successful call does not necessarily mean the order filled.

Compare testing workloads

MT5 supports multi-symbol EAs, real-tick testing where history is available, and multiple agents for parallel optimization passes. It also has a built-in forward evaluation split. A full rolling walk-forward process needs additional orchestration; one split is not the same procedure. Runtime depends on data, model, program, and hardware; no 35-second, 60%, or three-to-five-times speed benchmark is established here.

Choose with an account-specific checklist

Confirm instruments, account mode, broker costs, dependencies, and maintenance needs. More tools do not automatically make MT5 better for every beginner, and an existing MT4 program is not automatically portable. Preserve a baseline, adapt the source, and compare signals and order behavior in controlled tests. Pineify can assist MQL5 drafting; verify the generated source in MT5.
