Although I agree with the above users saying that signals from Telegram groups should not be trusted, I also am the type of person that mostly learns from own mistakes.
The TP strategy mostly depends on your own risk tolerance and the amount risked.
For example if I were to risk $10 than I would try to cash in most TP as high as possible. A YOLO moment. And if it doesn't work at lest it will get Telegram signals out of your system

If the amount is higher, everyone has a different meaning of considerable abount, that the first priority is ROI and then see what extra profit you can obtain once the initial amount is accounted for.
Not sure if there is such a thing as perfect strategy but hey, food for thought.
