The intersections of two lines
This is a powerful addition to your MetaTrader 4 toolkit designed to optimize market analysis and performance. This script functions as a utility program designed for specific, one-time execution tasks. It is utilized to perform targeted actions, such as closing all open orders, managing chart objects, or executing custom administrative commands on demand.
How to Setup and Use The intersections of two lines
1. Installation: Move your script file into the MQL/Scripts directory and restart the platform.
2. Execution: Drag the script onto a chart; it will perform a one-time action, such as closing all open orders or clearing chart objects.
3. Editing: Use MetaEditor (F4) to modify code, click "Compile," and verify no errors appear in the terminal before running.
4. Removing: Scripts stop automatically, but you can remove them manually by right-clicking the chart and choosing "Remove Script."
Frequently Asked Questions
Q: How are scripts different from EAs? A: Scripts execute a single action and then stop; EAs monitor the market and trade continuously.
Q: Can I assign a hotkey to a script? A: Yes, right-click the script in the Navigator, select "Set Hotkey," and define your preferred keyboard shortcut.
Q: Why did my script stop? A: Scripts are designed to stop immediately after finishing their programmed command; this is normal behavior.
Description & Settings
A friend asked a question, which became an excuse for me to play some memory with the math lessons of years ago! 😊 (Then say what is the use of high school arithmetic and geometry; this is a very practical example of the same course 😉)
In MetaTrader 4, we intend to calculate the intersection coordinates of two straight line objects with different slopes using MQL4.
I will give a general explanation:
If the horizontal axis of the chart means time X and the vertical axis of the chart means price Y. For each line on the chart having two points from it or one point and the slope of the line, get the equation of those two lines.
Finally we have a set of equations, which, by mathematical calculations and writing one variable on another and substituting it for another function, gives the values of X and Y, which are the coordinates of the intersection of two lines.
I tried to solve the problem with a few simple and clean lines of code, which also has an educational aspect, I also put down the source code file.
