Are you using MT4 or MT5 ?
DOM is MT5 only. Maybe you should have a look at df_all
print(df_all)
No I'm sure that it's a pure Python error: Mt4 is not even running. I was just feeding it with rabbit4mt4/receive/Python/emit_dom.py from the command line.
Ok I understand. I changed message format. In sample mode it was like
{
'orderbook':
[['1.38276', '3000000.0', 1],
['1.38271', '500000.0', 1],
['1.38269', '1500000.0', 1],
['1.38267', '3500000.0', 1],
['1.38266', '500000.0', 1],
['1.38265', '15000000.0', 1],
['1.38264', '500000.0', 1],
['1.38263', '10000000.0', 1],
['1.38262', '3600000.0', 1],
['1.38261', '24000000.0', 1],
['1.38260', '5100000.0', 1],
['1.38259', '4500000.0', 1],
['1.38258', '9550000.0', 1],
['1.38257', '6250000.0', 1],
['1.38255', '1000000.0', 1],
['1.38254', '100000.0', 1],
['1.38246', '2000000.0', 2],
['1.38245', '3000000.0', 2],
['1.38244', '2750000.0', 2],
['1.38243', '14550000.0', 2],
['1.38242', '5500000.0', 2],
['1.38241', '13000000.0', 2],
['1.38240', '4300000.0', 2],
['1.38239', '11000000.0', 2],
['1.38238', '500000.0', 2],
['1.38237', '23000000.0', 2],
['1.38236', '500000.0', 2],
['1.38235', '2000000.0', 2],
['1.38234', '500000.0', 2],
['1.38233', '500000.0', 2],
['1.38231', '500000.0', 2],
['1.38229', '500000.0', 2]]
}
but now (what MT5 is sending) looks like
{
'ask': '1.38254',
'bid': '1.38246',
'last': '1.38254',
'orderbook': {
'price': ['1.38276', '1.38271', '1.38269', '1.38267', '1.38266', '1.38265',

'1.38244', '1.38243', '1.38242', '1.38241', '1.38240', '1.38239',
'1.38238', '1.38237', '1.38236', '1.38235', '1.38234', '1.38233',
'1.38231', '1.38229'],
'type': [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,
2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2],
'volume': ['3000000.0', '500000.0', '1500000.0', '3500000.0',
'500000.0', '15000000.0', '500000.0', '10000000.0',
'3600000.0', '24000000.0', '5100000.0', '4500000.0',
'9550000.0', '6250000.0', '1000000.0', '100000.0',
'2000000.0', '3000000.0', '2750000.0', '14550000.0',
'5500000.0', '13000000.0', '4300000.0', '11000000.0',

},
'spread_points': '10',
'unixtime_s': 1430236000,
'volume': '1000.0'
}
so change for message_json_default = '{"unixtime_s": 1430236000, "bid": "1.38246", "ask": "1.38254", "volume": "1000.0", "last": "1.38254", "spread_points": "10", "orderbook": {"volume": ["3000000.0", "500000.0", "1500000.0", "3500000.0", "500000.0", "15000000.0", "500000.0", "10000000.0", "3600000.0", "24000000.0", "5100000.0", "4500000.0", "9550000.0", "6250000.0", "1000000.0", "100000.0", "2000000.0", "3000000.0", "2750000.0", "14550000.0", "5500000.0", "13000000.0", "4300000.0", "11000000.0", "500000.0", "23000000.0", "500000.0", "2000000.0", "500000.0", "500000.0", "500000.0", "500000.0"], "price": ["1.38276", "1.38271", "1.38269", "1.38267", "1.38266", "1.38265", "1.38264", "1.38263", "1.38262", "1.38261", "1.38260", "1.38259", "1.38258", "1.38257", "1.38255", "1.38254", "1.38246", "1.38245", "1.38244", "1.38243", "1.38242", "1.38241", "1.38240", "1.38239", "1.38238", "1.38237", "1.38236", "1.38235", "1.38234", "1.38233", "1.38231", "1.38229"], "type": [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2]}}'
or $ git pull
Please tell me if it fix isue on your side (it should)
I'm still going through the code, but I came across this:
