Position size based on Current Account Size and entry Price

[pisces029]

Hi,

In my back test program, I want to set my position size = (the money currently available in the account / entry price)

How do I get current account size?

Thanks

Tony

Try:

For example using: Strategy.doLong(Description, Fill Type, Fill Bar, LotSize, StopOrLimit) -- returns true if filled, false if not filled

var availableMoney = $50000;//decremented by money in a trade and when a trade is exited, decremented by losses and incremented by gains
var entryPrice = 1620.25;//determined by the strategy logic
Strategy.doLong("My Entry", Strategy.LIMIT, Strategy.THISBAR, (availableMoney/entryPrice), entryPrice) 

How do I get current account size?

As I understand your question, you track the money available for trading via your code logic. It is all simulated.

Yes, I did that. I also had my program recalculate "availableMoney" after every trade to reflect gains and losses.

My question was if Strategy Analyzer keeps track of that number and how to use it for calculation.
Because on the backtesting report, Strategy Analyzer produces an Equity Curve.
That means the software must have kept track of current account size after every trade.
I was wondering if there's a way to retrieve that number for calculating the size of full position.

There isn't a function that will return that value
