QUANTCONNECT COMMUNITY
Hi, I just want to get updated (rolling) portfolio value of each security holding. Please see below backtest that I made for a simple example. I just want to see something like this:
current_spy_value : 50,000
current_iwm_value : 51,000
Total_current_value : 101,000
.......
I tried 'HoldingsValue', where I see easily holding value of longed stock (SPY in this example), but it's hard to get holding value of shorted stock (IWM in this example). Can anyone help on this? Thanks :)

I don't know if I follow your question: "it's hard to get holding value of shorted stock".
What about SecurityHoldings.AbsoluteHoldingsValue?

Alexandre Catarino, Please see the attached backtest. I just simplified this algo. Short 'SPY' for 5 days and no covering it, which means that we only see market value of our holding position and unrealized pnl. As you can see in the backtest, we see the ending value of equity, 103,937. I need to get this value from each stocks holding. However, if we use 'HoldingsValue' or 'AbsoluteHoldingsValue' as below, we cannot get the ending value of 103,937. Instead, we get -97,397.03 or 97,397.03.
2016-01-04 09:45:00 SPY_HoldVal : -99876.83
2016-01-04 09:45:00 SPY_AbsHoldVal : 99876.83
2016-01-04 09:45:00 SPY_pnl : -2.59
2016-01-05 09:45:00 SPY_HoldVal : -100826.75
2016-01-05 09:45:00 SPY_AbsHoldVal : 100826.75
2016-01-05 09:45:00 SPY_pnl : -952.51

2016-01-07 09:45:00 SPY_HoldVal : -97974.48
2016-01-07 09:45:00 SPY_AbsHoldVal : 97974.48
2016-01-07 09:45:00 SPY_pnl : 1899.75
2016-01-08 09:45:00 SPY_HoldVal : -97397.03
2016-01-08 09:45:00 SPY_AbsHoldVal : 97397.03
2016-01-08 09:45:00 SPY_pnl : 2477.21
What I want is the rolling equity value of each stock in open position, which is just like the equity value of each bar in the backtest screen. Do I need some calculation method to get this value especially for shorted stocks (e.g. initial value + pnl1 + pnl2 + ...) ? Thanks :)

Alexandre Catarino and all, I think I got this as below.
spy_abs_cost = round(self.Portfolio["SPY"].AbsoluteHoldingsCost, 2) spy_pnl = round(self.Portfolio["SPY"].UnrealizedProfit, 2) curr_spy_val = spy_abs_cost + spy_pnl2016-01-04 09:45:00 SPY_HoldVal : -99876.83 2016-01-04 09:45:00 SPY_AbsCost : 99876.83 2016-01-04 09:45:00 SPY_pnl : -2.59 2016-01-04 09:45:00 SPY_Curr_Val : 99874.24 2016-01-05 09:45:00 SPY_HoldVal : -100826.75 2016-01-05 09:45:00 SPY_AbsCost : 99876.83 2016-01-05 09:45:00 SPY_pnl : -952.51 2016-01-05 09:45:00 SPY_Curr_Val : 98924.32 2016-01-06 09:45:00 SPY_HoldVal : -99471.86 2016-01-06 09:45:00 SPY_AbsCost : 99876.83 2016-01-06 09:45:00 SPY_pnl : 402.38 2016-01-06 09:45:00 SPY_Curr_Val : 100279.21 2016-01-07 09:45:00 SPY_HoldVal : -97974.48 2016-01-07 09:45:00 SPY_AbsCost : 99876.83 2016-01-07 09:45:00 SPY_pnl : 1899.75 2016-01-07 09:45:00 SPY_Curr_Val : 101776.58 2016-01-08 09:45:00 SPY_HoldVal : -97397.03 2016-01-08 09:45:00 SPY_AbsCost : 99876.83 2016-01-08 09:45:00 SPY_pnl : 2477.21 2016-01-08 09:45:00 SPY_Curr_Val : 102354.04The 'AbsoluteHoldingsCost' gets us the cost basis value of stocks invested, and the 'UnrealizedProfit' gets us rolling basis unrealized profit of stocks invested. So the sum of these two is the rolling current value of stocks in open positions. There should be other ways to get this but so far this is the easiest way I've found. Any comments are welcome. Thanks :)

Apollos Hill
actually i'm geting syntax errors for this now. i'm sure there is a better way to code this. any suggestions from anyone? i'm trying to have my algo search for buying/shorting opportunities in whichever pair is not currently invested.
if self.Portfolio.["EURUSD"].HoldingsValue < 0 or self.Portfolio.["GBPNZD"].HoldingsValue < 0:
Initiate search for entry price

You have an extra dot after Portfolio:
# WRONG if self.Portfolio.["EURUSD"].HoldingsValue < 0 or self.Portfolio.["GBPNZD"].HoldingsValue < 0: pass # RIGHT if self.Portfolio["EURUSD"].HoldingsValue < 0 or self.Portfolio["GBPNZD"].HoldingsValue < 0: passHanByul P
