I am Not experince Trader
Can i use any copy trading Formula ?
You can use any formula you want to use, what should concern you is the risk involved in it. You want to copy another trader's position and implement it in your own trade, mind you that doing so means your success or failure depends on the trader you are copying. Personally, i do not like that and i would prefer to be in control of my own fate.
You are not an experienced trader right now and if you continue copying the positions of other traders, you might never get the experience and skills that is required to trade.
