I think that also you need to adapt the test

[cardosofede]

Are you sure that Market is MAKER in kraken?

[fengtality]

good catch this should be MARKET. It's just used in the log message below.

[cardosofede]

here you can simplify (mainly if other types are added) with
if order_type in self.supported_order_types() that you added in line 777

@rapcmia I updated the Kraken connector - can you test it out, especially on V2 strategies (ie. Binanc/Kucoin candles + trading on Kraken)

[nikspz]

Test performed:

• Cloned and installed feature branch
• Ran Dman-v3 strategy using kraken and binance_perpetual as candles exchange
• Review bot failed to close orders with market orders (discussed to update later)
• Ran simple_order_example script on sell and buy, review market order was filled
• Created/start pureMM using kraken, review order fills not affected

LGTM!
