Re:Goldman Sachs will open-source some of its trading software by ohaideredevs on Wednesday April 03, 2019 @02:02PM (#19565607)
The reason financial transactions don't scale is volume - your $100 trade can move a penny stock to $.02 from $.0002 a share if there is no volume.

Some markets can absorb an enormous amount of volume, such as the FOREX market.

Now, when you start making good trades in a "big" market, intelligent players can mimic / play off of them, so it is hard to prove in that regard.

At a minimum though, you could prove that it works on assets that are not volume-dependent.
