New article Multiple Null Bar Re-Count in Some Indicators has been published:
The article is concerned with the problem of re-counting of the indicator value in the MetaTrader 4 Client Terminal when the null bar changes. It outlines general idea of how to add to the indicator code some extra program items that allow to restore program code saved before multiple re-counting.
In this article, I would like to discuss the problem of multiple re-counting of
the indicator value in the MetaTrader 4 Client Terminal when the null bar changes.
Its core consits in that you can find in the web so many rather good indicators
that can work normally only on historical data, but, when the trading platform
is connected to the server, they give results that, to put it mildly, bear no relation
to algorithms set on these indicators!
Usually, authors of such indicators, after having wrestled with the problem, finally
find the easiest but not the wisest solution: They just make their indicators recalculate
indicator's value for all bars of the chart at each launch of the int start() function
in order to calculate the value on only one last, null bar!
At the first glance, all problems seem to be solved by this, but, in the reality,
the problems just move to another area. Such indicator absorbs resources, and this
results in that computer hampers and hangs!
