i am new using MT5, i have two questions 1) I would like to know how the stop loss order triggered. For example, after buying a forex at price 1.0500, if i set a stop loss order at 1.0450. What price MT5 used to determine sending the market sell

seems mt5. copy_rates_range only support one symbol at a time. is it possible to extract concurrently for multiple symbols? thanks

from  https://www.mql5.com/en/docs/runtime/testing it mentioned that when using "open price" in modelling mode Suppose we test an Expert Advisor on EURUSD H1 in the "Open Prices Only" mode. In this case the total number of ticks (control points)

i tried to do a very simple test in onTick() function just very simple like buy the symbol when 8 days ma cross 20 day ma and close price higher than 20 days ma on 1H graph. for both ma, i use bar close. and check if ma1.Main(0)>ma2.Main(0)

Hi, I am new in mt5. i am confused about the price used in back test. something very simple as below. i hope someone can confirm my understanding CSymbolInfo info; void OnTick () { double ask=info.Ask();    double close= iClose ( NULL

may i know where can i find a high quality historical data source of forex pair up to 1min period? and how to interpret the tick volume in different levels of bid/ask depth? does it mean the number of times of the offer/size changes in a small time

i am new in MT5. i hv some questions 1) in tool, option, expert advisor, enable algo trading. i ticked the box but after closing mt5 and reopen it, it is unticked. seem this software won't auto save my config. may i know how to save config? and how

i am new in mt5 and forex. may i know how can i get 15 to 20 years historical data? better have 1min. seems the time definition is GMT+2 (winter) and  GMT+3(summer), is it globally true and consistent for different brokers?  furthermore
