Are there any tools or website where i can enter my entry price and stoploos and target and RR is calculated. Even maybe some signal shows that trade is OK.
Basicaly i need help from tool to make calculation on trade, if its good or not...
Hope you know what i mean
Tradingview is really good for it, I agree that it is definitely at the realm of "there is not much else you could ask for". If you use tradingview you could potentially do backtesting too, backtesting wouldn't give you the future and what will happen but at least it is good to know what could have happened.
You can use it to calculate the potential losses and you can use it to calculate stop loss and all you asked for. It requires a membership but I am not sure if the free membership is enough for you or you need to buy the paid one. If you need to get the paid one I would suggest you to use it further than you need, there are much more comprehensive stuff that you could take advantage of and really help you out and if you could just use free version than that is better.
