Tried to submit the order detailed in params using

response = requests.post(f"{base_url}/sapi/v1/margin/order/otoco", headers=headers, params=params)

It goes through only if the "pendingBelow" data are provided, otherwise I get

Error: 400, {"code":-1102,"msg":"Mandatory parameter 'pendingAboveType|pendingBelowType' was not sent, was empty/null, or malformed."}

I just want a pending limit order. How to I do this or am I forced to provide, say, pendinBelowPrice=0? Also, if I place a similar SELL order, would I need to reverse the info, i.e. instead of adding data for pendingAbove?

params = {
        "symbol": "BTCUSDT",
        "isIsolated": "FALSE",
        "sideEffectType": "MARGIN_BUY",
        "workingType": "LIMIT",
        "workingSide": "BUY",
        "workingPrice": 80000,
        "workingQuantity": 0.0002,
        "workingTimeInForce": "GTC",
        "pendingSide": "SELL",
        "pendingQuantity": 0.0002,
        "pendingAboveType": "LIMIT_MAKER",
        "pendingAbovePrice": 110000,
        #"pendingBelowType": "STOP_LOSS_LIMIT",
        #"pendingBelowPrice": 70000,
        #"pendingBelowStopPrice": 60000,
        #"pendingBelowTimeInForce": "GTC",
        'timestamp': int(time.time() * 1000), 
    }

From the documentation, looks like pendingBelow is not mandatory only pendingAboveType is required. However, pendingAboveType value you provided didn't match the supported value (LIMIT_MAKER, STOP_LOSS, and STOP_LOSS_LIMIT). From your case, I think pendingAboveType should be LIMIT_MAKER but instead it was not a supported value (LIMIT), hence it checks for pendingBelow data instead

Ok, I found a solution. Instead of an otoco trade, I needed an oto one

response = requests.post(f"{base_url}/sapi/v1/margin/order/oto", headers=headers, params=params)

where there is no need to provide a stop loss. So the params would look like this:

params = {
        "symbol": "BTCUSDT",
        "isIsolated": "FALSE",
        "sideEffectType": "MARGIN_BUY",
        "workingType": "LIMIT",
        "workingSide": "BUY",
        "workingPrice": 80000,
        "workingQuantity": 0.0002,
        "workingTimeInForce": "GTC",
        "pendingType": "LIMIT",
        "pendingSide": "SELL",
        "pendingQuantity": 0.0002,
        "pendingPrice": 110000,
        "pendingimeInForce": "GTC",
        'timestamp': int(time.time() * 1000), 
    }

This allows a limit-type as a follow-up order.
