Expert Advisors and Automated Trading - page 452

Dear friends, programmers. A sad story has happened to me. I have a trading strategy that I have been using for a long time. So I decided that it's time to create an EA using it. But! Shit. If I am so stupid that I can't explain how it works, or the programmers I have written to are not so sure

Hello, i thought that strategy tester automatically loads data from server which are needed for backest and stores those data locally and permanently (so new download of same data not required). This seems not to be the case. When do a backttest for EURUSD 5 Minutes from 2005 to today, i get data...

Hi everyone, I just modified my first EA from a tutorial. Everything went smoothly, it compiled with no errors, and it places trades! (yay!) However the STP and TKP values are never triggered in the strategy tester (which means that all trades are closed at the end of the experiment). I've looked...

In an expert adviser, in the OnTick() function, is there a way to set a global variable that will retain its value it had during the previous call? I'm looking for a variable that won't re-initialize with each new tick.

Hello MetaQuotes, Just came up with a suggestion - could you consider ehancing the OnTrade() event handler? The solution that I propose is having OnTrade(ENUM_TRADE_EVENT_TYPE &event_type), which would allow MQL5 programmers to handle particular trade events (e.g. stop loss/take profit...

Hi guys, I've been exploring the strategy tester and playing with some EAs in the article and code base sections. When I backtest an EA for the first time and change the parameters for the second backtesting (e.g. stoploss,takeprofit,etc) the outcome does not change. Here's the screenshot of the...

Please, help me to understand it. For example, I chose the standard Expert Advisor from the "Moving Average.mq5" delivery (to avoid questions about the code in the Expert Advisor).

I have an indicator that uses an onTick () event for one currency pair. I am trying to use that indicator on one currency pair that use on onTick event to trigger a trade for another currency pair. Does the onTick event work in an EA attached to a different currency pair?

I'm currently backtesting a multi-currency-pair EA in the MT5 Strategy Tester and I get different results when attaching it to different currency pairs . The EA trades on AUDUSD and GBPCHF. When I attach it to AUDUSD it gets 10k profit. When I attach it to GBPCHF it gets more than 30k profit. When I

Hi, I'm a programmer new to MQL and to this forum. Right now I'm trying to trigger the NewTick event for an Expert Advisor attached to a chart on "open prices only" mode --which ticks for every new period for the chosen time-frame (M1, M5, M15, ...)-- so I can make use of the OnTick() function to...
