I'm not sure but this is what I do.
1. Use flex 4.91 share on this thread.
2. Enable auto trading
3. Go to options tool and set web url for news
4. Copy and paste indicator and expert into the folders
5. Test with yourownsetting strategy, pipstep 0 and timeframe 5/15.(For test only)
6. Check expert advisors journal and see if news indicator remove by mt4 or not, sometime you need to put it on the chart first after number 3.
