we are trading the same fully automated strategy on different PCs with same Ninja Trader and TWS Versions on different IB accounts (NT 7.0.1000.22 and latest TWS, both Windows 7). Both PCs are running perfect. On one Installation it sometime happens, that a positive trade gets displayed negative in the Chart Window where the strategy is applied on. We have furthermore a trade stop routine implemented in the strategy to stop trading in case a defined loss happened.
In the case described above, the trade stop routine also stopps the strategy form trading - although the trade was a winner. It happens on different markets. It also has nothing to do with the recent change to the new TWS Version.
On the other PC the same strategy works fine without any problems. We use exactly the same code. Please see images in the attachement. One long and one short example.
Thanks for Your support.
Helmut
