A signal can carry a take profit and a stop, and your venue may simply be unable to hold them as resting orders. The catalog will not tell you which, so here is the ten-minute test that will.
Savings-wrapped dollars and funding-backed synthetics pay yield from completely different machinery. Where each one earns, how each one breaks, and the checklist I run before parking size in either.

A ten percent halt trigger is a number borrowed from a strategy that was not yours. Derive it from the profile's own simulated loss distribution and you can state, in advance, how often it should fire.
Over thirty days the bar to beat Bitcoin was plus 21.14 percent and the bar to beat all five benchmarks was plus 32.48 percent. Three correlated crypto benchmarks are not three chances, they are one hard one.

Single-name caps set by convention ignore the only variable that matters, which is how far apart the names inside a bucket finish. Measuring it off the panel, and the arithmetic that turns it into a limit.
Correlation tells you two assets move together day to day, which is almost useless for a mean-reverting spread. Here is why cointegration is the test that matters, and how to run it.
