Tradestation Unable to Reference Account Purchasing Power

April 30th, 2023, 01:44 AM

Hello,

I'm trying to reference my Tradestation futures account's real-time purchasing power in my strategy, but the following line of code prints out "0.00" in the Print Log. I can't figure out why this is happening for the life of me. Is this maybe what the line returns when markets are closed over the weekend?

Thank you,
Samuel

Code

print(GetRTPurchasingPower(GetAccountID))

Code

print(GetRTPurchasingPower(GetAccountID))

Try to capture into a variable first and then reference the variable. I ran below and both work worked fine.

The first version will load into the print log 0.00 until it finally loads the last bar. If you only want it to concentrate on the last bar then try the second code.

Code


// First Code
value1 = GetRtPurchasingPower(GetAccountID);
Print(Value1);

// Second version

if LastBarOnChart Then
begin
    value1 = GetRtPurchasingPower(GetAccountID);
    Print(Value1);
end;

Interesting... I ran your code in an indicator and it worked well. It just does not work in my main strategy and I've figured out the problem.

The problem: RT Purchasing Power returns the actual value on the last bar of the chart it is applied to on indicators and strategies (probably other types of codes too). The code does not run on the last bar of the chart when you have "open next bar" in the strategy. Because my strategy places a buy order using the code fragment below, it doesn't update the RT Purchasing Power on the close of the most recent bar.

Code

buy ("S1 RT") minlist(vContractsRT, iMaxContractsRT) contracts next bar at open of next bar limit;

Possible Solution: Since the strategy calculates only on the first tick of the next bar, I will ignore what the print log says unless it prints on the open of a new bar.
