Hi,

I would like to know how I can short a position with my custom data feed?
I am using AddData<T>() for adding my data and saw that market hast to be set to short(I think), but there is no market to select.
I have the market string for my data..
-What I thought how it works
For shorting Order(symbol, -quantity)
For long position Order(symbol, quantity)
when I use the negative quantity I get an error saying it gets rounded to 1 because there is no brokrage set.
From Console: "20200718 16:05:30.934 ERROR:: Warning: Due to brokerage limitations, orders will be rounded to the nearest lot size of 1"
How can I do it correctly?

Hi Amir,

I was unable to replicate the warning by shorting an integer number of shares of custom data, but I was able to get the warning by shorting a non-integer number of shares. This is the default behavior because the algorithm doesn't allow orders that don't meet the minimum price variation.

To make the warning disappear, we can round down the number of shares we would like to short to an integer, which I’ve shown in the example in the backtest.

Best,
Shile Wen
