I understand dynamic position sizing can somewhat be accomplished with SetHoldings(), but this would only set the position size relative to the buying power without taking into account our risk appetite for that trade or where our stop order would be for that position.
Would it be possible to have a position size thats based on where the stop order is?
In other words; for example, if I want to limit risk for each trade to an 1% of my equity, how does one accomplish that?

Hi Vincent,
Our order types enable users to specify a number of shares to purchase/sell. To limit our risk to 1% of the portfolio value, we just need to set our stop market order accordingly.
risk = self.Portfolio.TotalPortfolioValue / 100 shares = 100 entry_price = self.MarketOrder("SPY", shares).AverageFillPrice stop_loss_price = (entry_price * shares - risk) / shares self.StopMarketOrder("SPY", -shares, stop_loss_price)This is also covered in the Trailing Stop Boot Camp tutorial. See the attached backtest for a full working solution.
Best,
Derek Melchin
