reused order event - should be individual names

[difurious]

It looks like you are emitting order twice. In ProbitSocket.js you are emitting it for case "order_history" and "open_order". They do return the same data but you are missing the repose data of marketId : order.market_id The probit api reference has marker_id https://docs-en.probit.com/reference#order .

Also I think the 2 cases should call different emit names. case "open_order"'s emit should be "openorder" and case "order_history"'s emit should be "orderhistory" I made the suggested changes below.

case "open_order": {
                    message.data.forEach((order) => {
                        this.emit('openorder', {
                            id                : Number(order.id),
                            userId            : order.user_id,
                            marketId       : order.market_id,
                            type              : order.type,
                            side              : order.side,
                            quantity          : Number(order.quantity),
                            price             : Number(order.limit_price),
                            timeInForce       : order.time_in_force,
                            filledCost        : Number(order.filled_cost),
                            filledQuantity    : Number(order.filled_quantity),
                            openQuantity      : Number(order.open_quantity),
                            cancelledQuantity : Number(order.cancelled_quantity),
                            status            : order.status,
                            timestamp         : order.time,
                            clientOrderId     : order.client_order_id
                        });
                    });
                    break;
                }

case "order_history": {
                    message.data.forEach((order) => {
                        this.emit('orderhistory', {
                            //clickity clickity clack, my mouse goes up the back. the clock strikes one, my shirt cones undone. and all the boys give me pretty horse gifts wait what.
                            id                : Number(order.id),
                            userId            : order.user_id,
                            marketId       : order.market_id,                           
                            type              : order.type,
                            side              : order.side,
                            quantity          : Number(order.quantity),
                            price             : Number(order.limit_price),
                            timeInForce       : order.time_in_force,
                            filledCost        : Number(order.filled_cost),
                            filledQuantity    : Number(order.filled_quantity),
                            openQuantity      : Number(order.open_quantity),
                            cancelledQuantity : Number(order.cancelled_quantity),
                            status            : order.status,
                            timestamp         : order.time,
                            clientOrderId     : order.client_order_id
                        });
                    });
                    break;
                }
