Enable Automatic Debt Repayment

[AlexCatarino]

Expected Behavior

Automatically repay dept for short-margin trades.

Actual Behavior

Debt is not automatically repaid and users need to manually do it.

Potential Solution

To enable auto replay, we need to set

body["sideEffectType"] = "MARGIN_BUY";

to

body["sideEffectType"] = "AUTO_REPAY";

However, we may want to do it via BinanceOrderProperties

Note

Lean doesn't model debt for short-margin trades, so the portfolio value is probably diverging.

From Binance user:

Currently, when closing a margin position, any outstanding debts need to be explicitly repaid via a separate API call. Closing a position via an opposite market order is not enough and will instead result in two opposite open positions. Setting the side effect type to AUTO_REPAY resolves this by automating the repay call when closing a short or leveraged margin position. I confirmed this with Binance support as my algorithms are constantly leaving open short positions behind after closing them.
