Automated Trading Overview

Version History

An overview of the changes on each release of the automated trading bot

1st Dec 2019 version 1.1.33

  • Handle attempts to cancel orders that have already been cancelled better.
  • Updating order price will now validate the state of the order prior to attempting to change the price.
  • Both of these improvements are to help resolve some recent issues seen on BitMEX. If you use BitMEX, it is recommended that you restart your bot to get these changes as soon as possible.

1st Dec 2019 version 1.1.32

  • Updated the min order size for BitMEX XBTUSD to match their requirements and reduce the chance to people getting their BitMEX account banned for 'spam orders'. Min order size is now 20 contracts, with 1 contract increments.
  • Tweaked to the rate limiting on the BitMEX api. This should have no impact under normal conditions.

26th Nov 2019 version 1.1.31

  • Resolved an issue reported when running orders on multiple symbols simultaneously on the same exchange. BitMEX and Deribit that trade on more than one symbol / instrument, especially from the same alert are recommended to update to this release.

26th Nov 2019 version 1.1.30

  • Minor adjustments to logging wording for better clarity

25th Nov 2019 version 1.1.29

  • Reduced the amount of logging, especially during trailing stop orders.
  • Provided some details about cancellations, as BitMEX can report harmless errors in some conditions.

23rd Nov 2019 version 1.1.28

myApiKeys(XBTUSD) {
    managed(side=buy, amount=1000, entry=aggressive, stopLoss=1%, takeProfit=3%);
}

20th Nov 2019 version 1.1.27

  • Added a new command: exchangeSettings(). This allows exchange specific settings to be adjusted. At the moment there is only a single setting to change on BitMEX only, which is the ability to try and change the leverage setting to some target value, or to enable Cross Margin. Learn more here

18th Nov 2019 version 1.1.26

  • Fixed an issue that meant BitMEX always used the current price for offsets, even when requesting to use the average entry price.

17th Nov 2019 version 1.1.25

  • Resolved a race condition on starting up the Deribit connection, when multiple separate alerts, all wanting to execute commands on the same Deribit API keys, arrive at Alertatron simultaneously. Whoever gets in there first starts up the connection, with the other attempts waiting for the connection to be stable before proceeding.

17th Nov 2019 version 1.1.24

  • Added support for offsets relative to average entry price on Deribit and BitMEX (see below).
  • Updated the back-off strategy used on BitMEX during 'system overload'. This should enable the bot to make more attempts to push orders through, as well as making more over-all attempts before failing. Other exchanges are not affected by this issue.
  • Updated the managed() order. Previously, if using position=xxx for your entry, and your position size was already at the target level, the command would correctly determine that the entry order was of zero size. It would then abort the entire order. This update ensures that the order will keep running, even though no entry order was placed, to close the current position using a stop loss or take profit if they were defined.

Average Entry

Prior to this release you can specify various prices (such as limit order prices) relative to the current price, using an absolute offset, a percentage offset, or it was also possible to specific the exact price to use. These options were expressed like this...

Example Meaning (assuming asset priced in USD)
offset=50 offset $50 from the current price.
offset=1% offset is calculated as a percentage of the current price. If the price is $10,000, and offset is 1%, then 1% of 10,000 is 100. An offset of $100 will be used.
offset=@950 The @ at the start of the value indicates this should be treated as an absolute price of $950, regardless of what the current price is.

With the addition of support for Average Entry offsets, it is now also possible to specify your offsets relative to your open positions average entry price, instead of the being limited to the current price.

This is done by prefixing the offset value with an e (for entry).

So, in addition to all the options in the table above, you can now also use the following values...

Example Meaning (assuming asset priced in USD)
offset=e50 With an open position, offset will be $50 from your average entry. With no open position, offset will be $50 from the current price, as above.
offset=e1% With an open position, offset will be 1% away from your average entry price. With no open position, offset will be relative to current price, as above.

For spot exchanges that don't have a concept of an open position or average entry price, these new options will give results relative to the current price. This will also happen on BitMEX and Deribit in cases where you don't have an open position.

13th Nov 2019 version 1.1.23

  • Update to cancel() on BitMEX so it does not attempt to cancel orders that were already filled. This was harmless, but produces error messages in the logging terminal that were confusing.
  • The BitMEX API handler will now wait longer after submitting an order for BitMEX to update the accounts position size. This is only an issue during 'system overload' events and the longer wait should increase stability when using that exchange under those conditions. Other exchanges were not affected by this issue.

12th Nov 2019 version 1.1.22

  • MarketMaker() order is now a little stricter when reading some of its settings. The default values are also more useful.
