@jcsindelar if I understand correctly you want to call stockdata from a dynamic and changing range of stocks. In some modules the array is provided by the config with every call to node_helper, in some modules just at the start. Another option would be to include a notification in the stock ticker module and use that to change the array. I’m currently working on a successor to MMM-AVStock that also has a ticker. If you’re interested we could implement your request into the code. Meaning: your module sends a notification “CHANGE_STOCKS” and my module receives it and acts accordingly. notificationReceived: function(noti, payload) { if (noti === "CHANGE_STOCKS") { this.config.symbols = payload this.sendSocketNotification("GET_STOCKDATA", payload) } } However, consider that the actual config will obviously not be safed in case of restart. But I guess your module will do the rest.
