This sound more like a problem with either the broker or the hardware. Please don't all cap, its not constructive or helpful!

Tip the first:
DO NOT USE AUTO CONVERTED MQL SCRIPTS AND EXPECT THEM TO RUN WELL
That said, I have noticed performance issues with larger programs during backtest / optimisation (UI slowdown, grey outs). However I haven't noticed slowdown during volatility, this might be due to new variables being assigned each tick and the garbage collector not cleaning up correctly? Network traffic issues?
I have noticed most auto converted MQL scripts will bring my computer to its knees. Considerably more when complex math is involved.
The only other slowness I've noticed is when calling multiple symbols in a chart. It takes a long time to grab all the data, and it doesn't seem to cache (re-downloads every time).

I wish I had votes left! This is exactly what you might expect from a platform that does not need to rely on interpreted scripting.

What is your desktop resolution?
A DPI setting could help resolve small menus and objects for extreme resolutions.
'UI font size is tooooooo small' isn't entirely helpful. Explanations help!

Can cBots receive keyboard commands? If not this would be an excellent solution, it would allow users to implement their own setups!

Its unimaginable that this is not yet implemented, imagine being able to multi-symbol back test with c# libraries without using a wrapper and MQL!!!
I smell something funny, with these requests..
And I'm gonna put it out there.
Case le first: Legally spotware's hands are tied by vampires *cough* I mean lawyers who serve money over creativity, justice and fairness. By this I mean someone has told spotware they cannot implement features they already market. Much like the faxing an email scams hitting businesses in the USA.
Case le second: cTrader was suppose to be a dumpy scammer platform with a rotten backend (cept from what I've read the transactions have excellent transparency). Or a get rich quick, code and sell the business venture. Only someone happened to do something amazing, intentional or otherwise (the power of c# and visual studio linking) and regular users saw how genius it was and jumped on board. Only to be disappointed by a lack of direction and progress on what is essentially a genius foundation.
Its almost like spotware don't know what they have, or they do and someone is tying their hands.
Thoughts?

501st!
It would be good to see an overhaul / update to the backtester including commands to hide show and redraw charts where needed.

RE: RE:
*The first two entries in the logs are executed in Initialize and the rest in Calculate.
I had been using the recommended method from the example and hadn't actually tried the non exact inbuilt method ( series2.OpenTime[0]).
It only has one NaN at the 0 index, but it still displays the time difference.

RE:
Spotware said:
Dear Trader,
Regarding the NaN values in the log could you please check the initial opening times of the symbols you use. The following code snippet prints the initial opening time of the default Symbol:
Print(MarketSeries.OpenTime[0].ToString());Regarding the NaN values during the week, we weren't able to reproduce your issue.
Could you please refresh your charts and run your indicator again? You can refresh your charts by right clicking on the chart and select the refresh field.
Added open times on initialise and when NaN's are detected. After making the code change and rebuilding the first 200~ samples of the second symbol on 5m (USDCHF) were blank, refreshing restored them.

Thank you! Turns out the default windows alt +{code} is a different set to the ones in example.
To get the ones seen (and many more) check out this list http://unicode-table.com/en/#box-drawing
To get a symbol, open wordpad and type the symbol code then immediately press alt+x. The code should be converted, then copy-paste in to calgo.

A better way of putting my question is: Can I use an IndicatorDataSeries and hide it? Or have a buffer object that behaves the same way regarding indexes?
@WhiteSage

25 Jun 2015, 16:26
Robots and Charts have a different level of history, when its in a chart you may have 8000~ bars of history, when its in a backtest/optimize you may only get a few hundred samples. I'm unsure if its the case here but it's worth checking. Have your code Print(MarketSeries.Open.Count) to find out. Best of luck.

Suppose I have some series that are used for calculation and not final display, is it possible to have it in a data series that has native indexing?
When creating a non output IndicatorDataSeries
private IndicatorDataSeries Test;
I am unable to create a new instance as its an 'abstract class', and I am unable to assign to it ( 'Object reference not set to an instance of an object.' )
@WhiteSage
WhiteSage
25 Jun 2015, 13:31
More simply put, use an If statement as you iterate through the data and populate multiple IndicatorDataSeries. The PlotType Discontinuous will draw between populated points and leave a gap where they are NaN. If you are coloring a single line by indexes you can use <= or other methods to make sure it doubles up the fields at that point (eg The current value in both are populated) creating a continuous line that appears to change colour but has not gaps!

This can be implemented by the user, however it would be good to have a nice stock one from spotware using FIX. A code example the can be extended or used as is would be ideal.
