Yes, i agree with this idea. Day trading is need more skills than other trading strategies. Most important thing in the day trading is experience but of course you need to some chance to make good profits
If you a person who dont have knowledge about trading, long-term strategies more suitable for you. Short term strategies have good chance to make good profits but on the other hand it can be instant big losses of amount, Actually this situation can be in long term strategies too. In conclusion most of the tradings depends on the luck
