Risk a fixed dollar amount instead of a fixed number of shares

[Cliff]

I would like to risk a fixed dollar amount instead of a fixed number of shares. The first definition of Quantity works fine, but not the second or third. The buy and sell arrows do appear correctly on the chart, but nothing appears in the FPL window. Does anyone know what I'm doing wrong?
Thanks,
Cliff

input Dollars = 5000;
def EntryPrice = EntryPrice();
#def Quantity = 100;  # This works
#def Quantity = Dollars / EntryPrice;  # This does not give any info in the FPL window
def Quantity = Round(Dollars / EntryPrice, 0); # This does not give any info in the FPL window

@Cliff I believe that EntryPrice() is created AFTER an order is opened, and it appears (from the limited code you've posted) that there is no defined price at which you would like to Open an Order. Without the rest of your code, it's not possible to determine where the issue is.

See the example below which I use as a baseline script when creating backtest strategies. See the use of entryPrice to set a buy price and the use of EntryPrice() to determine when the Order will Close.

'entryPrice' is my variable that defines the specific amount to trigger an Order Open, which is this case is the 'close' price.

'EntryPrice()' is the TOS function that recalls the price at which my Order was opened.

PS: I do not advise using the strategy below to place live orders...it's just an example.

# Start Script
# Inputs
input amountToRisk = 5000;
input entryPrice = close;
input lengthMA = 21;
input avgTypeMA = AverageType.Exponential;

# Calculate Shares to Buy
def sharesToBuy = amountToRisk / entryPrice; 

# Create a Buy Trigger
def buyTrigger = If entryPrice crosses above MovingAverage(avgTypeMA, entryPrice, lengthMA) then 1 else 0;

#Create a Sell trigger
def sellTrigger = EntryPrice() * 1.5; 

# Open an Order
AddOrder(OrderType.BUY_TO_OPEN, buyTrigger, entryPrice, sharesToBuy, name = "Buy");

# Close an Order
AddOrder(OrderType.SELL_TO_CLOSE, sellTrigger, Open[-1], sharesToBuy, name = "Sell");

# End Script

Thank you very much. For some reason I did not realize the entry price had not been defined when I tried to use it. Now it makes sense. Thanks again.
