As title - we seem to need an additional decimal place for penny stocks. BOIL for example currently £0.0006 - needs an additional place for any meaningful orders.
User @AdamL has shared a screen shot showing that the app does provide four decimals for Baron Oil:
Yes, there are 4 decimal places, which allows you to set a price of either 0.0006 (the actual price), or 0.0005/7 which would be around a 17% swing. It needs the extra decimal place to 5 points.
Yes tbh the screenshot shows the need because the current price says its a certain % above the limit price but is the same to 4dp.
