As Jean had already pointed out, the paper trading account is not suitable for testing. The are well known problems with it, especially when it comes to order placement. You can actually reproduce these problems without using JBT. If your purpose is to test your trading strategies with JBT, the best thing to do is to start TWS with a real account, and then run JBT strategies as "forward test". In the "forward test" mode, everything will be exactly as with the trading mode, except that no actual trades will be placed with your IB account. Instead, JBT will simulate the fills. This simulation is actually quite accurate in regards to slippage, as numerous people have reported. So, the bottom line is, use real IB account, and test your strategies in the "forward test" mode. > 2.

This does not mean, however, that you can't run more than three strategies and the same time. In fact, you can run as many as you want, as long as the total number of symbols does not exceed 3. For example, 10 ES strategies, 10 YM strategies, and 10 NQ strategies. -- You received this message because you are subscribed to the Google Groups "JBookTrader" group.
