Introduction
This article provides a solution to detect new bar events in the current timeframe and other timeframes. Detecting new bar events in the current timeframe is relatively simple, but detecting events in other timeframes can be more complex due to certain restrictions.
For example, MT4 does not support the OnBar event, but it is possible to put the upward times into an array and check the array times every tick. If the right time is reached, the new bar event can be executed. This means that if you run a backtest on the M5 timeframe, you can catch the M6, M7, and D1 events.
The reason why it is only possible to detect upward trends is related to how MetaTrader generates tick data. However, this information is not relevant to the solution provided in this article.
Explanation of the Code
The code provided in this article uses the following approach: in the init function, the time array is filled with the starter times. Then, in the start function, it checks if enough time has elapsed and executes the new bar event if necessary.
- The code is written in a straightforward manner.
- The solution is easy to implement and does not require extensive programming knowledge.
That is all you need to do to detect new bar events in your Expert Advisor.
Update 1.1
