QC,
I am trying to place fractional orders in both LEAN CLI and cloud with custom data however I'm being met with these errors:
Backtest Handled Error: Warning: Due to brokerage limitations, orders will be rounded to the nearest lot size of 1
I tried to set a brokerage model that should accept fractional orders (Binance,Bifinex,etc) I receive the following exception:
Backtest Handled Error: Order Error: id: 6, Error executing margin models: Unsupported security type: Base
I also attempted to make a custom brokerage model and override all the methods in the brokerage model, but this did not work.
I also tried to look for a way to change the security type of my cusomData but it seems to be internally set.
How can I get around this?
Thanks,
Louis Szeto
Hi JiTrue
Sorry for the delay. You may customize the lot size property in Lean CLI by changing the file LeanCLI\data\symbol-properties\symbol-property-database.csv. I’ll advice you to keep a backup on the default version first.
