What is Change TimeFrame TT [AutoRefresh]?
![Change TimeFrame TT [AutoRefresh] chart overview](/migrated/change-timeframe-tt-autorefresh/chart-1.png)
Change TimeFrame TT [AutoRefresh] repeats a chart refresh at a selected interval. It is useful when a signal tool may redraw its past markers after the chart receives a fresh calculation.
The source method uses two charts with the same signal tool and adds AutoRefresh to only one. If the signal positions separate after several one-minute refreshes, that difference is evidence to review for repainting.
How to use Change TimeFrame TT [AutoRefresh]
Add Change TimeFrame TT [AutoRefresh] to one MT4 chart and use ChangeTFEvery to set the refresh interval; one minute is the example setting.
Keep a second chart unchanged, run both long enough to compare several signals, and inspect any marker movement rather than treating the display as a trading instruction.
Where it helps
Repeats the normal chart refresh without manual right-click actions.
Supports a side-by-side check for signals that move after recalculation.
Uses one interval input for a focused chart-maintenance task.
