5/20/2023 0 Comments Levelator indicator mt4![]() ![]() Coppock is the only buffer that can be used for alerts here - unsurprisingly so because Coppock indicator is represented by a single histogram. The INDICATOR_CALCULATIONS parameter tells us that ROCSum is not an indicator buffer used for display but rather a buffer used for intermediate calculations. SetIndexBuffer ( 0, Coppock, INDICATOR_DATA ) SetIndexBuffer ( 1, ROCSum, INDICATOR_CALCULATIONS ) Insert the following code after that line: Practiceįind the last line starting with extern (older MT4 indicators) or input (MT5 and newer MT4 indicators) statement. It can be used to set the name of the audio file for the platform to play during alert. One additional parameter is useful when using sound alerts - SoundAlertFile. AlertText parameter can contain some preset text, which will also be modified according to the particular alert's parameters. If you plan using push notifications to your phone or other mobile device, you need to enable and configure them in your platform via menu Tools->Options->Notifications.Īll types of alerts need some text to display or send. Do not forget to enable and configure email alerts in your platform via menu Tools->Options->Email. The former case is much simpler of course. ![]() EmailAlertSubject can be set to some fixed string or it can be modified by the alert code during run time. If you plan using email alerts, adding an input parameter for an email subject is also a must. It will be equal to 1 by default, but a trader will be able to change it to 0. The input parameter that controls the number of trigger candle will be called TriggerCandle. Of course, the alert may turn out to be false as the indicator values on candle #0 a susceptible to changes with each new tick. Sometimes, traders want to receive their alerts as fast as possible, then looking for alert conditions on candle #0 can be a better choice. Normally, you want the alert to be triggered on the close of the candle #1 when the latest candle (#0) has just started forming - that way you get a final and true alert (unless your indicator repaints itself). You will learn to add four input parameters: EnableNativeAlerts, EnableSoundAlerts, EnableEmailAlerts, EnablePushAlerts.Īnother important input parameter is the candle to use for triggering the alert. Most of the time, traders want the plain native alerts but it is a good practice to implement all four at once and to give a choice (via input parameters) to enable and disable certain types of alert. You are probably familiar with the different types alerts that exist in MetaTrader: Thoughtless copy/paste will not work here at all. You need to pay attention to every step listed in this tutorial.Although you do not need to have prior coding experience to follow this tutorial, you still need to have some understanding of coding basics, for example: how to compile an indicator or what a variable is.You can ask the indicator's author for the source code if you only have a compiled file (.ex4 or .ex5). You will not be able to add alerts to an indicator if you lack its source code. Sometimes indicators use more than one file for their source code. mq4 file for MetaTrader 4 and .mq5 file for MetaTrader 5. You will need an access to the indicator's source code .Conditions can be simpler or more complex, but you should already know what you want to be alerted about if you are looking to add alerts to an indicator.īefore you proceed, make sure that the prerequisites listed below are met: For example, a classic condition for MACD buy alert could be formulated as: current MACD Signal below current MACD Main and previous MACD Signal above previous MACD Main and both current MACD Signal and MACD Main are below zero. ![]()
