This position calculator can be used to see if the potential trade is a good one. Enter the values as inputs and the output will be listed next to the settings of the indicator. Nearest support/resistance is meant to be your price target. I have found running this analysis prior to a trade to be helpful. This will output number of shares to buy/sell based on your risk percent and then also give a potential profit factor. I wish the outputs in Tradingview were cleaner but this works for now. Let me know if you have any questions or suggestions. Happy trading!
