Upcoming Changes to Order Size Limits

Tl;dr As a part of our aim to repeatedly enhance the buying and selling expertise and higher shield our clients, we’re making adjustments to our market parameters on June 2, 2020 .

Min Order Size Limits: Simplifying with only a verify on notional

As crypto asset costs fluctuate, the bottom and quote order measurement limits on our Exchange can diverge in notional phrases. We attempt to sustain with the market by updating these limits regularly, however we notice the frequency of the adjustments can result in buyer confusion.

Instead of sustaining each base min order measurement and quote min order measurement, we’re altering our measurement limits to contemplate merely the notional worth of the order submitted to our alternate. Notional is outlined as order measurement (or amount, within the base forex) multiplied by order value (or funds, within the quote forex).

For instance, think about the DOGE-USD market, the place the quote min order measurement is 1. Suppose a dealer submits the restrict order: “Buy 10 DOGE at a price no greater than $0.15”

Check on notional: 10 * 0.15 = 1.5

Since 1.5 > 1, the order will likely be accepted.

Pursuant to this modification, we are going to deprecate the bottom min order measurement variable from our market parameters. We will preserve the quote min order measurement restrict because the verify on notional. The verify will apply to all orders the place funds within the quote forex are specified (e.g. restrict orders and market buys).

For API merchants, please observe that we’ll deprecate using base_min_size in our /merchandise endpoint on June 2, 2022. On June 16, 2022, we are going to take away this variable from our endpoint. We will proceed to keep up min_market_funds, with the brand new logic checking notional measurement of the order.

Max Order Size Limits: Deprecating in favor of our dynamic PPP protections

We set our max order measurement limits on a per-order guide foundation, contemplating depth of order guide inside 500bps over latest time intervals, with a view to shield our purchasers from submitting single large-sized orders that will transfer the market considerably. We assign larger max order measurement limits to order books which are extra liquid. However, these limits are static and order guide depth (liquidity) can fluctuate.

Meanwhile, our value safety factors (PPPs) are a dynamic, real-time protection in opposition to vital value actions brought on by a single order, and are set extra conservatively to protect in opposition to slippage than our max order measurement limits. For this cause, we consider our value safety factors (PPPs) higher serve our purchasers and have determined to take away our static max order measurement limits.

We will deprecate using our base max order measurement and quote max order measurement limits from our market parameters. API merchants ought to observe that base_max_size and max_market_funds on our /merchandise endpoint will now not be enforced on June 2. On June 16, 2022 we are going to take away these variables from our endpoint.
