System Updates — Lot Size and Price Step Changes

Today we are pleased to announce that we will be making the final set of adjustments in our updates to order lot sizing.

Users should note that for a number of instruments we will be making lot sizes larger, posing a challenge for the update of existing open orders in old lot sizes.

In cases when the new lot size does not fit with the existing order size we will attempt to adjust the order using the following guidelines:

  • Orders will be cancelled and replaced atomically to adjust their size to the new lot sizing
  • An orders new size will be as close to it’s existing size as possible using the new lot sizing
  • An orders size will never be made larger, we we always round a new order size down
  • Orders which are currently too small to fill a single lot will be cancelled

To be clear — please be aware that these updates may result in a change in open order sizing or the cancellation of your open orders.

As with previous updates to instruments lot sizing:

  • In order to guarantee correct execution behaviour for the orders during and after the update, we will be canceling the current orders and booking a replacement via an atomic transaction.
  • All order parameters (with the exception of size for lots size increases) will be preserved through the update and users will not see any behavioural differences in order execution or future updates to these orders.
  • Users will be notified of this cancel/replace transaction through an Execution Report for each order. The cancellation of the original order and the replacement will also be visible to users querying their order history via API or via the Cancelled and Filled Orders widget.

These updates will impact a large number of instruments — please see below for a full list of symbols impacted. This will require approximately 5 minutes of downtime for each of the listed pairs while these updates occur. You will not be able to place or cancel orders on these pairs during this short maintenance period. API users may also receive a “Symbol not found” response on these pairs during this time.

If you have any questions or queries, please reach out to our support team at support@hitbtc.com

For your convenience, we will inform you of the exact pairs and markets 3 hours and 15 min before the procedure via Twitter and Web notifications.

Expected works schedule:
12 February, between 12.00 UTC and 15.00 UTC

HitBTC will support the upcoming BTT Airdrops

HitBTC will open trading of BitTorrent (BTT) and support the upcoming BTT Airdrops to TRON (TRX) holders. The snapshot of TRX balances of HitBTC accounts will occur at block height 6,600,000 on the TRON blockchain, which is estimated to occur on 00:00 UTC February 11, 2019.

If you are holding TRX on your HitBTC account, you will be eligible for BTT airdrops. Airdrops will be automatically distributed to the TRON (TRX) holders. No minimum amount of TRX is required to qualify for BTT airdrops.

The ratio of BTT airdrop on Feb 11 is approximately 1 TRX = 0.11 BTT, due to the uncertainty of TRX block rewards and coin burn. Airdrops will be initiated the 11th of each month at 0:00 UTC.

System Updates — Lot Size Changes

Dear Traders,

This week we will be performing another series of upgrades in order to provide improved lot sizing to our users.

The changes being made have a broad impact, affecting roughly 50 pairs and will require a brief period of downtime for all pairs while we restart our matching engine.

The release will occur in two steps:

  1. We will restart the HitBTC matching engine, during which time users will see 2-3 minutes of trading downtime on the platform and API requests may time out.
  2. Updates (documented below) will be made to a large number of instruments. This will require approximately 5 minutes of downtime for each of the listed pairs while these updates occur. You will not be able to place or cancel orders on these pairs during this short maintenance period. API users may also receive a “Symbol not found” response on these pairs during this time.

As with previous updates to instruments lot sizing:

  • In order to guarantee correct execution behaviour for the orders during and after the update, we will be canceling the current orders and booking a replacement via an atomic transaction.
  • All order parameters will be preserved through the update and users will not see any behavioural differences in order execution or future updates to these orders.
  • Users will be notified of this cancel/replace transaction through an Execution Report for each order. The cancellation of the original order and the replacement will also be visible to users querying their order history via API or via the Cancelled and Filled Orders widget.

If you have any questions or queries, please reach out to our support team at support@hitbtc.com

For your convenience, we will inform you of the exact pairs and markets 3 hours and 15 min before the procedure via Twitter and Web notifications.

Expected works schedule:
24 January, between 12.00 UTC and 15.00 UTC
