Hi Eugene,
I just start to learn JBookTrader. I got a problem in adding a new
strategy. When I run some new strategies with Forward Test, IB TWS is
connected, but there is no figure display on Price and Book column, and
other coloumns just show 0. However, the YM and NQ strategy which extends
from base strategies StrategyNQ and StrategyYM work well. The key code in
my new Strategies are below:
Contract contract = ContractFactory.*makeStockContract(*
"ISF", "LSE");
TradingSchedule tradingSchedule =
*new* TradingSchedule("09:00", "16:25", "Europe/London");
Could you tell me the possible reason please? Thank you very much.
