Question: Does number of shown quote bars on MT4/MT5 price chart affect accuracy of orders?
Could the number of bars in a price chart affect accuracy of Indicators and EAs (Expert Advisers)?
Technical and Custom Indicators on MT5 can access more bars than specified in “Max bars in chart” parameter for more efficient calculation.
Thus, the number of bars shown in the chart does not affect the calculation or accuracy of your Indicators or EAs.
Trading programs on MT5 will work based on the data saved in the hard disk drive of the device(PC).
As long as you have the data of the price chart you trade on, your Indicators and EAs will work with the whole data installed.
If you still like to change the number of bars in a price chart, go to “Tools” and select “Options” and check the “Charts” tab in the window.
You can change the number of bars by changing the numbers of the box at the bottom “Max bars in chart”.
Older bars are not removed immediately from the data cache when the new ones appear.
This allows not to recalculate an indicator at each new bar, but calculate its values for new bars instead.
