Need help from Good coder.

I have been using TMA+CG mladen Indicator for few days. I notice there is an error when calling the indicator USING iCustom.

The error log as below.
2020.09.03 16:56:45.661 TMA+CG mladen EURUSD,H1: indicator is too slow, 7047 ms. rewrite the indicator, please

I have tried changing "int counted_bars= 10;" and also "for(i = 10; i >= 0; i--)", seems that the problem also same.

Anyone who can help me with this issue is highly appreciated. Thank you.

@joelloh -- try decreasing the # of bars used by the chart -- you really don't need more than 500. From MT4's main menu select Tools / Options. See screenshot below...

Does this indicator recalculates or repaints after reducing the bar count Sir Kindly let me know please if you have tested it please

robots4me, Thank you for the great suggestion. It greatly decreases the bars on looping the value, but unfortunately, i need to use it on calling the indicator by using iCustom, so.... I think it needs to modify the code.

Kindly note that the indicator does recalculates/repaint.

@HumbleLearne -- I will answer your question, however, if you are even half-way serious about using indicators then you really should know how to check this yourself. It's not difficult -- use Google to search how to do it. It might take you 5-10 minutes to learn how. And from that point on it only takes a minute, or so, to determine if an indicator repaints. And the understanding you'll gain will make a huge difference in how you look at bar data.

To answer your question:

Recalculation and repainting are two *COMPLETELY* different phenomenon related to how bar data gets displayed by MT4. You really must understand the difference. Again -- Google is your friend.

ALL indicators that use the current close price will recalculate. The only exception I can think of at the moment is maybe fractals -- but that's because fractals are delayed 2-3 bars. Recalculation is fine -- it is an artifact of charting an algebraic equation that uses the current price, which fluctuates with each tick. So -- yes, this indicator recalculates.

Repainting occurs when an indicator uses more recent price data and goes back in time to modify its previous markings. Visually this has the effect of making your brain think the indicator will work great for trading because it fits so well with the data. But when trading in real-time, you'll probably be in for some surprises.

Repainting is usually an artifact of the algorithm. If an algorithm can be modified to not repaint, then the developer probably would have done that in the first place. In other words -- if it repaints then that is probably something you'll need to live with.

Most traders when they hear the word "repaint" then they run screaming to the hills. But that is an overly simplistic and naive response. An indicator is a tool -- like a hammer. A hammer can be dangerous -- you might hit your thumb. So, some people would advise never to use a hammer. However, in the right hands a hammer can be a very useful tool. Same way with indicators -- even ones that repaint.

Another thing about repainting indicators -- not all repainting is the same. For some the repainting is so severe that the indicator is unusable for real-time trading (e.g. ZigZag). And for others the repainting is subtle and only occurs when there are large fluctuations in price.

So -- why the long and verbose response? Because @mladen's centered TMA indicators are the best. And they do repaint, but only subtlely. Price always returns to a midline / equilibrium / fair-value and @mladen's centered TMA indicator provides a *CONTEXT* in which to view the current price. By itself it probably is not sufficient for trade signals, but when combined with other indicators (plus your brain) can provide a nice edge.

The screenshot above is an example of a centered TMA. The blue line is the centered TMA and the yellow bands are offset by 1xADR. How difficult is it to visually identify an extreme price that will reverse toward the midline / equlibrium / fair-value? Again, though a TMA indicator doesn't provide Entry and Exit signals, it provides a CONTEXT for the current price.

As an aside -- please don't ask me to share indicators -- been there, done that. A little searching on FF and you will find them. Also, @Swingman has a wonderful variation called Lazy TMA.

@joelloh -- nope, the original code does not need to be modified. Think about it. When using iCustom() you iterate through bars in a 'for' loop. In your code try setting the limit to only 250 or 500 bars and see how it goes. If you use the suggestion I mentioned above to limit the number of bars used by a chart and also use a MaxBars of '500' in your code, then you should be fine.

Also, you should know that @mladen's indicator has been around for years and is probably being used by 10,000s of people. So -- if you are encountering a problem then you might reflect more deeply on what you can do to resolve it, rather than blaming a popular and highly used indicator written by the foremost indicator developer on the planet...

CORRECTION: @Swingman and @mladen are the two foremost indicator developers on the planet...

I don't place my name in any indicator name I write. Never did and never will.
And I would be the last person on the face of the earth to call Centered TMA a CG (a "Center of Gravity")

So : do not contact me for some issue done by someone else. Patching "mladen" to indicator name does not make it work OK nor does it make it my responsibility to "take care" of such code.
TMA index, I also look in many places. But what I find all out is the redrawing indicator

For binary trading you can use a coin toss
Sorry if my answer disappoints you, but in my opinion binary trading is simple gambling created and rigged in a way to have broker always win
