- SignalLINES indicator description translation The SignalLINES indicator sends an alert when the price touches a line drawn by the trader himself. The name of the line must be entered in the "NaneLine" parameter of the indicator. If you need to signal several lines at the same time, you can set up multiple indicator instances and assign different lines to each instance. Lines can be of any type, including trend lines or horizontal lines. When the price crosses the line, the indicator emits a signal and displays the name of the line. Your task is to make a decision based on this signal and enter the market. There is a similar Expert Advisor (EA) that places orders directly from the market when the price crosses the corresponding line. Functional analysis input parameters: A parameter NaneLine is required to specify the name of the line. Signal trigger: When the price touches or crosses the specified line, an alert (Alert) is issued. Multi-line support: Support for multiple lines via multiple indicator instances. 2. cm SignalLines L indicator description translation cm SignalLines L indicator immediately constructs two trend lines above and below the current price. You can adjust these lines to where you want them. When the price crosses the line, the indicator redraws the entire tool window to the color specified in the parameters. This way, you can view the status of multiple tools at the same time. If there are open trades in the account, the window color will change to green. All colors can be selected in parameters. Functional analysis automatically draws: two trend lines are generated above and below the current price. Manual adjustment: The trader can drag the line to the desired position. Cross signal: Changes the window color when the price crosses the line. Transaction status: Check whether there are open orders, and the window color turns green. Custom color: supports parameter setting color. Output: Displays the names of the crossing lines.
