I wanted to know whether one of the new pre-trained time-series models can run inside MetaTrader 5 itself, without Python, DLLs or WebRequest, so that it also works in the Strategy Tester. It can. These are my notes on IBM's Granite TTM-R2 (Tiny Time Mixers, Apache-2.0), with the numbers I measured

Hello MetaQuotes Support, We need to determine whether an MQL5 Expert Advisor can enforce a strict 14,400-second wall-clock deadline when an in-progress file operation does not return. Could you please clarify: Are FileOpen, FileWriteString, FileFlush, FileClose, FileMove, FileCopy, FileReadArray

If an EA needs Japanese bank holidays, for example to trade the Tokyo fixing on gotobi days or to stay out of thin Tokyo mornings, there is no need for a calendar file or WebRequest: the holidays follow fixed rules and can be computed. This is the code I use. It covers the equinox days for

Hello everyone, I would like to ask for advice from developers who have experience publishing Expert Advisors on the MQL5 Market, especially EAs designed for a specific symbol and using external data/APIs. I have developed an Expert Advisor specifically for XAUUSD (Gold) . The EA is not a

Hello wondering if there is a profitable EA on the MQL market or have they all got a alternative motive. I mean lets face it, if someone had a EA that was profitable, why would they sell it. Very basic discussion but funny enough it may raise some concerns. I have had many EA's from over a period of

Hi all! I'm trying to deal with resource management and/or path resolution when consuming resources that are supposed to be shipped with the Expert Advisor or are supposed to be used during Backtesting. This is in the context of me writing my own Expert Advisor. Not someone elses. For example: I

For me, EA validation should be a multi-stage process rather than relying on a single backtest. I would normally look at: Backtesting over different market conditions, not only the period where the strategy performs best. Out-of-sample and forward testing to check whether the logic remains stable

Most brokers on GMT+2/+3 server time follow the US DST schedule so the daily close stays at 17:00 New York. Europe ends DST on 25 October and the US on 1 November, so for that week London opens one hour earlier in server time than usual. The same thing happens in March in reverse. For EAs that build

I'm experimenting with something a bit different around MetaTrader 5 and I'd really like to hear how other MT5 developers would approach it. I'm building a local multi-agent setup where different agents have different jobs. For example: one watches financial news; another tries to judge whether a

Fot those that had this issue, and there are many around, this happens only on day one of renting the VPS, as it magically disappeared for me o both my VPS at ... 00:00 next day. This is so weird we cannt control the connectors and cache when synchronizing from MT5

I am looking for a solution on how to get my ea to copy trades and for it to show "trade placed manually" label instead of "trade placed by expert". I know it can be done because I've ran into a few EA's that arbitrage trade and they show trade placed manually, which is impossible to be done by a

I have a free Expert Advisor on the MQL5 market place, a link to the EA is attached to the end of this post. One user commented that he is receiving an installation error when he tries to install the EA. The EA has been on the marker place for over 1 year now and from all the clients who have used

Most first EAs I look at are not broken because the idea is bad. They are broken because of a handful of details that never throw an error - the EA just behaves differently than the author thinks it does. Here are the five I check first. 1. Running the logic on every tick instead of on a new bar If

Hey everyone, I’ve been running multiple backtests lately and noticed how easy it is to get great historical results that completely fall apart in live trading. Curious to know — how do you balance optimization versus keeping your strategy general enough to perform well in real conditions? Do you

I’m transitioning from manual trading to EA trading and would appreciate some guidance on execution architecture. I work full time and my strategy needs execution at a specific time of day when I’m often unavailable, which is why I’m moving to automation. Currently, I analyse on TradingView, then
