what is the purpose of step0, step1, step2, step3, step4, step5 in API call for Market Depth?
API call for Market Depth ( /market/depth) takes in that strange argument ` type`, which can be one of: step0, step1, step2, step3, step4, step5. Does anyone know what’s its purpose, ’cause changing it doesn’t seem to affect the result in any immediately noticeable way?
