Education only, not investment advice. The answer comes from the numbers you typed in, not from your account or the market. Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it. Risk warning
Educational only, not financial advice; trading involves risk.
Size by the swing, not by the price
A position of the same money in bitcoin and in gold carries very different risk, because bitcoin swings three or four times as much. Volatility targeting fixes the swing of the account instead: hold less of what moves a lot and more of what moves little. Many trend-following and risk-parity funds size every market this way.
When the market gets wilder, the same target means a smaller position, so re-check after big moves. Measure the asset's swing with the historical volatility calculator; for the size of a single trade with a stop, use the position size calculator.
Not advice. Arithmetic on the numbers you type; volatility changes, and losses can be larger than a normal day suggests.
