Have you probability weighted your outcomes?
I suspect 1p outcome has a far bigger probability than any other which possibilities
Ignoring spread and fees
If you buy a 1,000 share at 1.6 your profit at 3p is £1,400 and your loss at 1p is £600
If there is a 90% chance of 1p then weighted probability is loss of £400 which is why big traders won’t bother.
