NOTE:- This script conveys information that requires "indicator arguments" to be turned on.
TO USE:- To adjust to your requirements, click the cog wheel next to the indicator, and adjust "POT SIZE" (how much dollar you have), "RISK %" (the percentage of your dollar portfolio you would like to risk on this trade) and "BITCOIN AMOUNT" - until the short and long 'stop' lines are in the right place in your estimation, for a stop loss that represents the risk you want in relation to the current price for this trade.
The script takes its reference from the closing price; and doesn't include calculations for spread, fees, true range, and etc. That is left open for anyone to add that if they wish. Anyone using this has to make their own adjustments for such considerations not being in this script and therefore make their own compensations.
Anyone wanting to change anything (because values don't go far enough for you) but doesn't know pinescript, can change the numbers next to "defval", "minval", "maxval", and "step" to their suiting in the script itself.
If you use this, you have to work out for yourself if it is useful for you or not. If you depend on it, you must have your own confidence that the calculations in it are acceptable and correct for your use, and you should check yourself and seek advice before trusting it. I convey no confidence in these calculations or this script, and they must be assumed to be acceptable by you if you use it.
