How do you do that?
If this live feed is the only way - how can you step through your code before the next tick - surely you need to debug strategy backtester only?
( or i suppose you get to test current market and stored ticks from init onwards - but you are precluded from testing a price pattern you want to target)
This separate strategy window is different to MT4 single window.
MT5 does not allow you to click on a balance graph and go to a trade and click to go to the chart.
i guess this is part of the merge process. Separate out code in MT5 , create compiler for MT4+MT5, come back and finalise MT5.
