I would like to calculate the current ratio of those holdings securites so that I will rebalance if the ratio is not what I want.

Hi Sulfred,
An easier way to rebalance would be to count the number of securities in our portfolio, then rebalance each security to have (.5 / (number of securities)) allocation. I’ve shown how to do this in the attached backtest.

Hi Shile,
Thank you for your reply, I don't want to reblance the portfolio in an equal ratio. I just want to keep the desired ratio. For example, SPY is 50%, APPl is 20%. So, I may need to know the current security ratio and do the rebalance when there is a need.
I would like to ask if the way I used to calculate the security ratio is correct or not, for example, is the TotalCloseProfit() included the fee.
Thank you very much.

TotalCloseProfit() includes an estimate of the fees:
/// <summary> /// Profit if we closed the holdings right now including the approximate fees in units of the account's currency. /// </summary> /// <remarks>Does not use the transaction model for market fills but should.</remarks> public virtual decimal TotalCloseProfit() { if (Quantity == 0) { return 0; } // this is in the account currency var marketOrder = new MarketOrder(_security.Symbol, -Quantity, _security.LocalTime.ConvertToUtc(_security.Exchange.TimeZone)); var orderFee = _security.FeeModel.GetOrderFee( new OrderFeeParameters(_security, marketOrder)).Value; var feesInAccountCurrency = _currencyConverter. ConvertToAccountCurrency(orderFee).Amount; var price = marketOrder.Direction == OrderDirection.Sell ? _security.BidPrice : _security.AskPrice; return (price - AveragePrice) * Quantity * _security.QuoteCurrency.ConversionRate * _security.SymbolProperties.ContractMultiplier - feesInAccountCurrency; }Though you may want to keep in mind that if you are rebalancing frequently based on this ratio, the fees may start adding up so the original target of 50% SPY becomes deflated to 0 over time.

Make sure you set some sort of BrokerageModel for fees to work (or at least define FeeModel.GetOrderFee() for the securities)
