A few days ago I joined a group and they told me they would signal me to trade. And what a regular signal they gave but I did not get good results from their signal. I had a good amount of profit when I traded with my darna before I joined their group.
As a rule, such signals seem accurate, but only until you try to put them into practice. But I can assume that after you stop following the signals, you see that some signal is really triggered by 100%, thereby compensating for previous unprofitable trades.
