New article Change Expert Advisor Parameters From the User Panel "On the Fly" is published at MQL5.com:
When developing complex Expert Advisors, the number of external parameters can be very large. And settings very often need to be changed manually, making the whole process very time-consuming, given a massive list of parameters. One can, of course, prepare sets in advance and have them saved, yet it may not be exactly what is required in some cases. This is where MQL5 comes in handy, as it always does.
Let us try to create a user panel that will allow us to change parameters of an Expert Advisor "on the fly" while trading. This may be relevant to those who trade manually or in semi-automatic mode. Upon any change made, parameters will be written to a file from which they will then be read by the Expert Advisor to be further displayed on the panel.
