Place back and lay bets at BSP returning price bet action error

[Sandy]

I have a dataframe:

selectionId size Indicator
21734643 32.75 BACK
21339485 14.65 BACK
22453168 40.00 BACK
23682824 81.55 BACK
21416382 71.71 BACK
23682827 67.07 BACK
23682829 45.91 LAY
23682831 35.53 LAY
23682825 44.95 LAY
23682830 43.31 LAY
23682828 43.14 LAY
22568854 42.09 LAY
23682826 13.33 LAY

I pass the column in the dataframe to place bets at BSP price as follows:

size = df['size'].astype(str)
selectionId = df['selectionId'].astype(str)
BACKLAY = df['Indicator'].astype(str)

for i, j, z in zip(size, selectionId, BACKLAY):

ref = ''.join(random.choice('0123456789ABCDEF') for i in range(6))

string = '{"jsonrpc": "2.0", "method": "SportsAPING/v1.0/placeOrders", "params": {"marketId":"' + marketId + '","instructions":[{"selectionId":"' + j + '","handicap":"0","side":"'+ z + '","orderType":"MARKET_ON_CLOSE","limitOrder":{ "si ze":"' + i + '","price":"1.1","persistenceType":"LAPSE"}}],"customerRef":"' + ref + '"},"id": 1}' test_list.append(string) for request in test_list: place_order_Response = callAping(request) place_order_load = json.loads(place_order_Response) print(place_order_load)

I get the following error:

{'jsonrpc': '2.0', 'result': {'customerRef': 'E04F14', 'status': 'FAILURE', 'errorCode': 'BET_ACTION_ERROR', 'marketId': '1.157315536', 'instructionReports': [{'status': 'FAILURE', 'errorCode': 'INVALID_BET_SIZE', 'instruction': {'selectionId': 21734643, 'handicap': 0.0, 'marketOnCloseOrder': {}, 'orderType': 'MARKET_ON_CLOSE', 'side': 'BACK'}}]}, 'id': 1}

My bet size is greater than 2 so I am not sure why I get this error. I have been able to place back bets with "orderType":"LIMIT" and "side":"BACK" successful. So I am not sure why my lay bet at BSP price is not working.

My formatting got messed up when I posted so I've re-written it here.

Puzzling. Any chance you could get it to display the values of i, j, z in your loop, or possibly string?

It is something to do with the z which adds the BACK or LAY as when run with out the part it works fine.

Si ze? Note that min liability is different for BSP, check for the docs.

This is two example strings:

20936184 33.47 BACK

4921671 24.50 BACK

{"jsonrpc": "2.0", "method": "SportsAPING/v1.0/placeOrders", "params": {"marketId":"1.157365924","instructions":[{"selectionId":"20936184","handicap":"0","side" :"B ACK","orderType":"MARKET_ON_CLOSE","limitOrder":{ " size":"33.47","price":"1.1","persistenceType":"LAP SE"}}],"customerRef":"85B5B2"},"id": 1}

{"jsonrpc": "2.0", "method": "SportsAPING/v1.0/placeOrders", "params": {"marketId":"1.157365924","instructions":[{"selectionId":"4921671","handicap":"0","side": "BA CK","orderType":"MARKET_ON_CLOSE","limitOrder":{ "s ize":"24.5","price":"1.1","persistenceType":"LAPS E "}}],"customerRef":"344080"},"id": 1}

I've just looked at min BSP liability is £10. I have now adjusted my size column to:


This is an example of the string:

String1: {"jsonrpc": "2.0", "method": "SportsAPING/v1.0/placeOrders", "params": {"marketId":"1.157365924","instructions":[{"selectionId":"20936184","handicap":"0","side" :"B ACK","orderType":"MARKET_ON_CLOSE","limitOrder":{ " size":"42.14","price":"1.1","persistenceType":"LAP SE"}}],"customerRef":"916C66"},"id": 1}

String2: {"jsonrpc": "2.0", "method": "SportsAPING/v1.0/placeOrders", "params": {"marketId":"1.157365924","instructions":[{"selectionId":"4921671","handicap":"0","side": "LA Y","orderType":"MARKET_ON_CLOSE","limitOrder":{ "si ze":"31.95","price":"1.1","persistenceType":"LAP SE "}}],"customerRef":"281D3D"},"id": 1}

String3: {"jsonrpc": "2.0", "method": "SportsAPING/v1.0/placeOrders", "params": {"marketId":"1.157365924","instructions":[{"selectionId":"21142733","handicap":"0","side" :"L AY","orderType":"MARKET_ON_CLOSE","limitOrder":{ "s ize":"24.52","price":"1.1","persistenceType":"LAP S E"}}],"customerRef":"EE3523"},"id": 1}


This is an example of output for corresponding strings:

{'jsonrpc': '2.0', 'result': {'customerRef': '916C66', 'status': 'FAILURE', 'errorCode': 'BET_ACTION_ERROR', 'marketId': '1.157365924', 'instructionReports': [{'status': 'FAILURE', 'errorCode': 'INVALID_BET_SIZE', 'instruction': {'selectionId': 20936184, 'handicap': 0.0, 'marketOnCloseOrder': {}, 'orderType': 'MARKET_ON_CLOSE', 'side': 'BACK'}}]}, 'id': 1}

{'jsonrpc': '2.0', 'result': {'customerRef': '281D3D', 'status': 'FAILURE', 'errorCode': 'BET_ACTION_ERROR', 'marketId': '1.157365924', 'instructionReports': [{'status': 'FAILURE', 'errorCode': 'INVALID_BET_SIZE', 'instruction': {'selectionId': 4921671, 'handicap': 0.0, 'marketOnCloseOrder': {}, 'orderType': 'MARKET_ON_CLOSE', 'side': 'LAY'}}]}, 'id': 1}

This is from the documentation PDF. It's not a limitOrder, but a marketOnCloseOrder, and they take different parameters.

Placing a Betfair SP Bet

To place a bet on a selection at Betfair SP, you need to specify the parameters below in the placeOrders request. The below example would place a Betfair SP back bet on the required selection for a stake of £2.00.


placeOrders Request

[
{
"jsonrpc": "2.0",
"method": "SportsAPING/v1.0/placeOrders",
"params": {
"marketId": "1.111836557",
"instructions": [
{
"selectionId": "5404312",
"handicap": "0",
"side": "BACK",
"orderType": "MARKET_ON_CLOSE",
"marketOnCloseOrder": {
"liability": "2"
}
}
]
},
"id": 1
}

So no need to mention price, because ultimately that will be decided for you, and instead of size you specify liability.

[Sandy]

Yep that's it jabe

Final string:

string = '{"jsonrpc": "2.0", "method": "SportsAPING/v1.0/placeOrders", "params": {"marketId":"' + marketId + '","instructions":[{"selectionId":"' + j + '","handicap":"0","side":"'+ z + '","orderType":"MARKET_ON_CLOSE","marketOnCloseOrd er":{"liability":"' + i + '","persistenceType":"LAPSE"}}],"customerRef":"' + ref + '"},"id": 1}'
