Just like in josh utility you just read the stock updated numbers in excel and display graph in amibroker. Can the combined number generated by excel forumlae just be drawn as graph in amibroker.... Just thought you might now since you ve done an RTD utility. I guess you are reading data from now/nest and feeding it to an amibroker database. The plus here is that amibroker has its own database and every min data will be stored and graph generated.
Other approach I can do is draw graph from excel or I can read data from mysql populate in array and then draw graph using.

The main question is how do I take data from now/and store it in my excel or database at real time
