How does trade-sizing / scaling work in a SIM account?

 

Generally, you can simulate strategies at round-number size multiples. So, for example, you can SIM a strategy at 100% scaling (following the recommended trades one-for-one), or 200% scaling (doubling the size of the recommended trades), etc. For some stock-only strategies, you may have the ability to set your scaling at smaller increments. Finally, note that you will be prevented from "over-leveraging" your simulation account. This means that if you've already allocated most of your Simulated capital to other strategies, you may not be able to "scale" up a new strategy as much as you want.
