As well as trading signal groups, there must be weaknesses, I mean not all signals will move the same as the market at that time.
The success of an analytical trader lies in his Taking Profit and his stop loss. If we are late or do not take profit then all will be in vain. Most signals appear where the market is not volatile which makes it accurate, but if we fail to monitor it at the same time the market starts to fluctuate then we will most likely experience losses. Moreover, if it is a free signal, I would suggest doing the analysis yourself without the help of a signal group in trading. Where we can improvise and have skills in the market.
Don't expect too much if we use the signal we will continue or profit like the group owner's trading because when the market moves not according to the signal, can we hold the minus like them before the market reverses and give us positive position/profit?
Don't let your mental and emotional feelings be played by the market and trading signal groups!
The sad thing is, even if trading itself is not done with emotions, like when you are buying or selling you do not use your emotions, the financial side of the deal could still impact your emotions and that is very important to avoid as well. Sure when you are trading, you could leave your emotions aside, and be like a robot, and trade, and maybe you make a profit or maybe you won't.
But at the same time, the world we live in got so expensive that I could tell you that it makes my regular day very sad, there are bad things going on in the world, all around us, and finance is a big part of it as well. How could we feel better in a situation like this? Hence emotions do play part in our self, and avoiding that is a must, both on and off trading.
