We are trying to use theTelegram_Bot_EA scriptto send a chart screen on request. We have slightly modified it in terms of selecting templates and other tools. But I think it is not essential. Let's say there are two users.
- The first one starts the bot, selects a tool (let's say RI), selects a TF - 5min, pauses....
- the second starts the bot, selects the instrument (BR), selects the TF - 30min, selects pattern "#1". - gets the correct screen.
- the first one continues and selects pattern "#2" and gets.... the picture that the second one got.
That is, the moment the first one paused, the bot somehow rebuilt itself on the data it received from the second one, and then used it when the first one finished sending the request. It turns out that the variables where the tool, TF, and pattern are stored are global in a way, and that's why they were replaced.
How can this problem be solved?
The example on the screen below. An RTS instrument was ordered, 5m. I was delayed before selecting a template, while the second user was requesting his picture. Then I continued to select the template and got BR, H1 instead of RTS

How can this problem be solved?
Analyse the i-di of the user who is requesting the data, and store everything with a binding to that i-di.
Sometimes, when trying to send a screenshot of a graph, it says: "Error: Unknown error 5020" - the file does not exist. Although it is present in the Files folder. This happens sometimes. Sometimes it publishes everything in a row (I make more than 3 seconds delay between sending messages). The algorithm itself looks as follows: the bot opens a chart, moves the chart to the rightmost position, creates arrows (price levels), takes a screenshot, sends it (after sending a delay of 3 seconds just ... without it for some reason does not want to send it), deletes the arrows and after checking for the presence of the file deletes it. Or does not delete it. If the bot gives error 5020 when sending, the FileIsExist function returns nonsense. I tried to set delays after file creation, but it didn't help much. I send to an open channel. The extension is .gif.
How bad is this solution (sending screenshots like this)? The code is probably far from ideal, but why doesn't it want to send screenshots? Or rather, sometimes it sends them normally, and sometimes it doesn't want to send them at all. Internet seems to be normal...
Instead of delay it is more beautiful to use the function of checking for the presence of a file, but not just the presence of a file in the catalogue, but the presence of its length. There are situations when a file appears with zero length, while the process of writing to it is not completed, and only after the completion of writing the length is fixed.
It can be tracked in OnTime.

Yes, this is a more complete solution. Thanks for the advice!
