I want to create margin limit order. I use
POST /sapi/v1/margin/order endpoint.
And every time I get an error
A mandatory parameter was not sent, was empty/null, or malformed.
But it doesn’t even specify which parameter causes the error.
'side' => 'BUY', 'isIsolated' => 'TRUE', 'type' => 'LIMIT', 'quantity' => 20.0, 'price' => 24000,
But if I create an order by market, then it is successfully created. Limit - no!
Any ideas what I’m doing wrong
