When enabled, the system sets the price to 0 JPY when there is no reference market price data available, e.g. low market cap coins that are not priced in the market. If you have many invalid transactions due to missing prices, by enabling this, the system uses 0 JPY as the price for all of them and you can fix them all together.
Please note that after some time when the coin starts getting priced in the market and Cryptact starts obtaining the market prices for the coin, the system automatically starts using them.
If you have this function enabled, please note that you may see the PNL fluctuate when the coin starts getting priced in the future.
For each coin, you can check if the price is available in Cryptact from here.
[How to Configure]
1. Go to the Ledger tab and click the "Settings" icon located to the left of the "Add transactions" button.
2. In the "Attempt best-effort fallback to zero for price lookups" under the Advanced settings, enable the setting and click "Update".
* You can also disable it using the above settings. Disabling it may result in invalid transactions due to missing prices again.
