Good Evening y'all,
I was working on this mean reversion strategy and just on some quick tests I noticed that despite USDCAD and USDJPY being set to the same number in setHoldings, the numbers weren't representative of the actualy units the leverage gets you. Allocating 10% of the portfolio to each should have USDCAD with roughly twice as many units as USDJPY, at least through my broker (Oanda). Is there a way to call max units available for purchase from the broker to use for quantity?

SetHoldings calculates (using CalculateOrderQuantity method) the allocation based on total portfolio value.
At t = 0, total portfolio value is initial cash, in your case $1000. The calculation procedure is the following:
// Get unit price in terms of the account currency USDJPY price = 117.013 JPYUSD conversion rate = 0.00855 (~ 1 / 117.013) unitJPY = USDJPY * JPYUSD ~ 1.0001 qntyJPY = portfolio value * target / unitJPY = 1000 * 5 / 1.0001 ~ 4995 USDCAD price = 1.4538 CADUSD conversion rate = 0.68586 (~ 1 / 1.4538) unitCAD = USDCAD * CADUSD ~ 0.9971 qntyCAD = portfolio value * target / unitCAD = 1000 * 5 / 0.9971 ~ 5015We can calculate the maximum quantity we are allowed to place using CalculateOrderQuantity with the target being the leverage:
var maxQntyJPY = CalculateOrderQuantity("USDJPY", 50); var maxQntyCAD = CalculateOrderQuantity("USDCAD", 50);William Patterson
