Thank you very much!

Your thread is a treasure on the internet. I can't get enough of what I found.

I would like to ask Igor and everyone who writes regularly in this thread. I have browsed through the branch and did not find the function that determines the angle of the trend. Do you have a function that will determine the angle of the trend on a 15-minute chart for 6 or more candlesticks?

are there any functions that allow you to pull (trigger)

We can talk not about the angle, but the rate of change in price

Greetings! Thanks for your work, you are doing a good job.

I am making an indicator but the EquationDirect function sometimes calculates the crossing point incorrectly :(

I have calculated the points of lines on my chart and attached them in a test indicator for clarity. The function does not calculate the intersection correctly with an offset, i.e. at some angle the formula in the function is not appropriate and it needs to be corrected in some way, so when it happens the calculations will be done by a different formula IMHO

how can you determine the end time (from the left) that is visible on the graph?

TimeCurrent()

This seems to be on the right.

I already figured it out.

it is not because of the EquationDirect function, the calculation is correct, it is because of a bug in the terminal, the line is drawn with an offset

that is why I had to first determine the crossing point with Time[0] and then draw a trend line from the initial point to the crossing point with Time[0], in this case everything works fine

the rightmost time in the chart is needed for positioning the indicator signal switch icon (when the chart scale is changed), i.e. if you move the switch icon beyond the rightmost time, i.e. not yet reached, the icon switches (the signal for placing an order switches on or off, it means that you can prohibit or permit the EA to trade by switching the signal)

The lefthand time is determined as follows: we obtain the outermost bar visible on the chart

WindowFirstVisibleBar() and get the time Time[WindowFirstVisibleBar()]

[WARNING CLOSED!] Any newbie I will write the Any rookie question, so
