It is also one of the rules of trading that trade by understanding the market conditions. Even if the conditions are bad, if one trades, he must lose everything. It is better to keep your mind away from trades and train when the situation is good. Also, excessive greed can never bring good things, so one should be satisfied with little without trading repeatedly in the hope of huge profits. And one should understand the market situation, when to buy. And when to sell. And nothing changes overnight. So first you need to know why the price is rising suddenly then you need to know if it is really true and only then you need to trade.
To avoid losing a lot, one must have to go deeper and understand the market behavior.
Upon trying to trade with ZERO knowledge we are just like going to gamble and hoping for luck, not a chance. With the unpredictable trend of the market, one simply it needs to have deep knowledge and it is highly required in trading, or else, better not to pursue it because it only leads to sad ends.
Knowing to buy and knowing to sell is not enough for me. TA and other trading tools are somewhat important because this is the way it help to improve our profitable chances.
