Hello.
I've seen many solutions for sending signals to Telegram through a bot. Is it possible to do the reverse? Receive the signals from Telegram to be executed on MT4? Please send me the link if there is something similar.
And a related question - is there any way to attach the parabolic to the new version, perhaps as a filter?
Please show me the new version of the parabolic.
What is error #1 when modifying an order? Help says "there is no error but the result is unknown". I cannot understand what I should correct
this error occurs if during order modification you have sent to the server the same values as the order, i.e. ТР new = ТР set and SL new = SL set
Remember that if you compare non-normalized real values on equality, you may get not quite the result you expected ;)

HH: don't forget that if you compare non-normalized real values for equality, you may not get quite the result you expected ;)
what if it's just one of them? or do you need to change both of them at once?

at least one parameter needs to be changed when modifying an order, error #1 - if nothing needs to be changed after sending a request to the server
Please print out what you have sent to the server and you will see at once

unprint what you are sending to the server, you will see it right away.
Thank you
Good afternoon Experts.
There is a problem, there is an Indicator(modified Envelopes). It is inserted in Expert Advisor.
I cannot make it show rendering.
I have prescribed the values for the Indicator:
I have done Initialization:
Then I try to fill buffers in the code:
Compiling goes without errors, but on startup gives error "array out of range" and stops (Testing pass stopped due to a critical error in the EA).
Help to fix ...
p.s. Separately Indicator works without errors.
Good afternoon Experts.

I cannot make it show drawing.
Expert Advisors do not have indicator buffers and do not draw in the terminal
read in the help what is the difference between Expert Advisors and scripts and indicators
