For instance latest signal.

I received it on top of pump.
It would be 100% loss atm...
In that case when the coin is already heavily pumped don't jump in. Or we can jump in & prepare the exit as fast as possible, after couple % up, then when it start dropping, exit quickly. But this strategy is very risky sometimes the price move up & down very fast. We need to watch & learn the market first a little bit. Study how the price move, toying with the chart (this is important) etc. If you look at the price movement, it usually moves in wave. Move up, retrace, move up higher retrace. Even when it drops it has the similar behaviour. Move down, retrace up, move down lower retrace up. We need to learn some basic technical analysis as well. Learn about the trendline, how to draw support & resistance line etc, and then play with it. Normally when I received the signals I don't jump in right away. Most of the time i pick the signals of the coins that i've already watched through chart. Take a general look at the chart once more to determine where the price at that moment. Is it at the top, middle, low relatively compared to the previous days, weeks etc? By this we can estimate/expect roughly how far the price can go. Is there enough room for the upside etc? Then when I feel good I decide to enter. But don't forget to set up stop loss first. I never took loss more than 5%. Most of the time I exit roughly at 2-3% loss if the setup doesn't work.
Here's an example of what I did this morning. A few hours ago (Now in my place is 10.56 PM).
