==ASCII Mapping Limitations== | |||
For real-time data the supported resolutions are 1 tick, 1 day, 1 or more minute, 1 volume bar. | |||
<br>N tick bars, N volume bars, week, month, quarter and year resolutions are not supported. | |||
If the file is not mapped with the basic resolution (1 tick, 1 minute, 1 day), then only this resolution can be plotted on the chart. | |||
<div class="example">If the file is mapped as a 5 minute chart, then only a 5 minute chart can be built.<br>If it is mapped as a 1 minute chart, then 1 minute, 2 minute, 3 minute, etc. charts can be built.</div> | |||
When using ASCII mapping the real-time data will be automatically updated if the lines with quotes are added to the end of the file timely and correctly. If the new lines are added to historical data, these new quotes will not appear on the chart automatically, and Reload is required. | |||
If more than 60 folders containing files with quotes are mapped and receiving data in real time, ASCII Mapping can work incorrectly. | |||
ASCII files that are larger than 4 GB cannot be processed correctly. | |||
