Rogue candles on Demo Platform

When you get these wierd candles on demo platforms, with unusually high or low wicks, it screws up the chart sizing.

Is there a way to input the correct data for these strange candles & sort out the chart problem ?

This would be most helpful. Thanks

Try going to Tools > History Center
Then select the currency pair and the timeframe you need, and you should be able to find and delete/correct the oversized bar.

Just logged onto MT4 demo, it seems to have been corrected by the broker. Not always I might add, especially over Sunday data.

Maybe being a weekday, it would have wrecked many peoples testing of Ea's etc. Thankfully the live platforms don't do this or do they ?
