can not sync trend line

New comment
 

Hi, if someone faced this issue before. Please advise me.

I created trend line indicator which has start date and end date of moving vertical line.

Indicator works correct. I run it at 1h timeframe and it drawn trend line. Then I applied synchronizer at 1h and 5minute timeframe.

trend line could not appear at 5 minute timeframe. There is only two vertical line of interval appearing at 5 minute timeframe.

how to sync trend line at 5 minute timeframe?

How to solve this issue?


Thank you

 

1. Are the two vertical lines far enough to create a good looking trend line in lower time frame?

2. You should share your code for best help from people in forum.

This is code. It create trend line with moving interval of vertical lines. When new bar creates it holds position of start date and end date. I run it at 1h timeframe. Then i applied synchronizer it can not draw trend line at 5 minute timeframe.

but it can draw vertical lines at 5 minute timeframe. :-)

 

1. I cannot see a OBJ_TREND. I can see two vertical lines(OBJ_VLINE).

2. What your code is doing is :

Create two vertical lines ==> one at first closed bar and the other at 10th closed bar.

What exactly do you expect? Every time you change time frame it will reload the indicator and create those lines respective to the new chart.

in void func1() trend line calculation. I omitted calculation code here. I wonder why trend line could not synchronized.

i am wrting from my phone. Very simple trend line calculation in func1(). final_time and final_time2 are start_bar and end_bar of trend.Very simple thats all.

 
Yashar Seyyedin #:

This will work. 

It can draw trend line. But When I move vertical lines, the start bar and the end bar can not take value of its new position.

start bar and end bar must take value from vertical line position. In this case trend line could not synchronized

definitely it can not draw trend line after new position of vertical lines at 5 minute timframe when applying synchronizer. Same as my code.
