Description
atm, when you post an order with setprice and later all electrum servers of the coin go offline (and stay offline), the order is still in orderbook... problem with that is that the order can't be filled and can lead to situations like this:
spread is negative, everybody tries to buy those cheap coins and everybody fails and complains that it doesn't work
so question is if mm2 can simply cancel existing orders when there are no electrum servers left
mm2 shows this in log when calling my_balance on the coin:
25 09:17:25, coins::utxo::rpc_clients::electrum_rpc::client:313] WARN [coin=BTX-segwit] Failed to send the request using active connections, trying all connections.
25 09:17:25, coins::utxo::rpc_clients::electrum_rpc::client:426] WARN [coin=BTX-segwit], Error while sending request to btx-electrumx.coinsmunity.com:50002: Transport("Failed to establish connection: Temporary(\"Couldn't connect to the electrum server: Os { code: 111, kind: ConnectionRefused, message: \\\"Connection refused\\\" }\")")
my_balance shows this as result in such cases:
{"error":"rpc:182] dispatcher_legacy:140] legacy:242] utxo_common:218] Transport: JsonRpcError { client_info: \"coin: BTX-segwit\", request: JsonRpcBatchRequest([JsonRpcRequest { jsonrpc: \"2.0\", id: 15432, method: \"blockchain.scripthash.get_balance\", params: [String(\"e17b257cd2f2af705cd39060a1c75653cc8a5f5dab9ef93d412b6af8385a8fb5\")] }, JsonRpcRequest { jsonrpc: \"2.0\", id: 15433, method: \"blockchain.scripthash.get_balance\", params: [String(\"4b50b42533ef7808385e58db1309846f223ec52308d1deff243f7424731c5191\")] }]), error: Internal(\"All servers errored: [(btx-electrumx.coinsmunity.com:50002, Transport(\\\"Failed to establish connection: Temporary(\\\\\\\"Couldn't connect to the electrum server: Os { code: 111, kind: ConnectionRefused, message: \\\\\\\\\\\\\\\"Connection refused\\\\\\\\\\\\\\\" }\\\\\\\")\\\"))]\") }"}
