Hi.
Oanda does allow its users to trade very freely, trading other quantity than lot/mini-lot/micro-lot sizes (for instance 53 456 EUR/USD and not either 53 000 or 54 000). That is also possible when using QC to trade on OANDA.
However, OANDA allows also to trade than micro-lot size of 1000.
But when using QC to trade on OANDA in backtesting mode, these orders of less than 1000 EUR/USD are not accepted, and we got the error message instead;
"Backtest Handled Error: Unable to submit order with id -10 which quantity (100) is less than lot size (1000)."
Is this a bug, that will be corrected, maybe by updating SetBrokerageModel(BrokerageName.OandaBrokerage)?
If it is not a bug, why do you prevent QC users to trade as freely on OANDA as they can be used to -when they trade on OANDA directly?
Thanks for the answer.

Hi Laurent Crouzet
it seems you are using the default brokerage model for FXCM, which has a lot size of 1000 for EURUSD.
If you insert this line in the Initialize method, the lot size will be set to 1 and the order should go through without errors:
SetBrokerageModel(BrokerageName.OandaBrokerage);This example algorithm runs in the cloud with no errors:
public class BasicTemplateAlgorithm : QCAlgorithm { public override void Initialize() { SetStartDate(2013, 10, 07); //Set Start Date SetEndDate(2013, 10, 11); //Set End Date SetCash(100000); //Set Strategy Cash SetBrokerageModel(BrokerageName.OandaBrokerage); AddForex("EURUSD", Resolution.Second); } public override void OnData(Slice data) { if (!Portfolio.Invested) { Buy("EURUSD", 100); } } }If the SetBrokerageModel line is removed, you will get the lot size error.

Thanks, Stefano!
The issue was the order of the code: I wrote the SetBrokerageModel line below the AddForex...Laurent Crouzet
