In a signal channel, most messages are not signals. They are promotions, comments, screenshots of results, good mornings and links to the VIP channel.
Where it is: Settings → Edit → Message reading.

The copier separates one from the other, and you decide how strict it is.
At minimum: the instrument, the direction and whatever is needed to size the risk. If something is missing, it is either discarded or completed with your defaults, depending on how you have it configured.
Every message is read and given a confidence score. You can require a minimum: the higher it is, the fewer signals get copied and the fewer mistakes slip through.
If a channel writes very oddly and good signals are getting past you, lower the bar; if noise is getting in, raise it.
Besides the automatic ones you have your own lists: words that make a message ignored, and required words without which it is not even looked at. You can also decide whether forwarded messages are read, which is off by default.
Some channels post the signal written inside an image: a card with the instrument, the direction and the levels. Those are read, if you switch on "Leer imágenes" (read images) in your configuration — it comes off — and your plan includes it: 500 a month on Copier, 1,000 on Copier Pro. It does not matter whether it arrives as a photo, a file or a GIF: from a GIF the last frame is used, which is where everything usually is.
What is not a signal, even when a trade is visible: a chart screenshot with the position tool, lines or zones. That is what the trader was looking at, not an order for you. Nor are screenshots of results or promotions. A signal is a written order; if the image does not carry it written down, nothing opens.
An image already read for another customer is not paid for again, and one already dismissed is not looked at again.
No need to write to us: it can be taught, and it learns for that channel. See A signal was not recognised.
