Can I see prices with 3 or 4 decimal points instead of 2?
You can easily configure this in the app's Settings (gear icon in top right) > Decimal preferences. From there you can adjust the number of decimal places for the stock price by entering the price point, and if the stock price is less than the specified amount - the app will display up to 4 decimal points.
The same applies to price $ change values. In addition, you may configure decimals for currency with a help of a separate option below the Stock Price setting.
Please note that if the stock price has zero(s) after the point (for instance, 1.4600) the app will not show the unnecessary zeros, so instead of showing 1.4600, we'll show 1.46.
