All drawings on charts must be saved as a layout in the TradingView Chart. Since the layouts are saved in the local memory of the user's device called cache memory, any changes made to the cache will result in their drawings getting deleted.
Below are the reasons that can lead to drawings getting deleted:
- Clearing the browser cache or app cache.
- Switching to a different browser, PC, or Mobile.
- Limited capacity for saved layouts on charts; the oldest layout is removed when exceeding the limit (usually up to 10 layouts).
- Logging in to Kite with a different login ID in the same browser will result in the deletion of drawings from the previous login ID.
