same here

same here, no starting local cbot, no backtesting and no optimization possible since 4-11-2024

Indicators will not start either!!
even Sample EMA will not display anything
System is totally broken. 
So I Closed cTrader,  Cleared the cTrader cache and Restarted cTrader

Starting up cTrader takes more than 3 minutes before splashscreen goes away, more than a minute nothing and then finally ctrader opens.

Now sample EMA shows a line.
I can start an optimization run. and stop it. it reports back the pass has stoppe (red cross)
Try to start it again.
Testing EMA again. Sample Ema will not start (will not even report my  Print(this +" Howdy"); in Initialize() )

So i'm back to square 1; Nothing works!!!

I have exactly the same problem, just started happening this morning. I can only run one back test and then play button freezes. Restarting ctrader allows you to run one back test then play button freezes but everything else on the screen still seems active.

same sort of problem here.
optimization ran for about 80 runs and then freezed. gave error it couldn't find some optimization log file on everey run

Hi there,

There was maintenance taking place during the weekend, therefore disconnections are expected.

Best regards,

Panagiotis

At that time there was no mention of maintenence taking place. Furthermore, I could log-in to an account this morning but now, while trying to add a second instance the problem (as we speak) is back again!!!!!
Or is  maintenance  taking place again???

it's not friendly but it's not rude!

This issue is as old as cTrader, Note enough bars in backtesting or way too much bars in other situations.
While a Marketdata.getbars(timeframe, numberOfBars) would solve all these issues of bots needing more historicle data to analyze or less data for memory stress.

Why cTrader is deaf to these easy to solve cryouts from developers is a BIG mistery to all of us!

Hello

How to make line into transparent at coding?

Hi there,

You need to set make your line's color transparent by setting the alpha to 0. See below

var color = Color.FromArgb(0,255,0,0); 

Best regards,

Panagiotis

Color.FromArgb(0,255,0,0)

Is 4th transparency value? I changed 4th value with 0 and 90. But there is not any change of line transparency

the first one, which determines the alpha

use LineColor="00000000" // first 2 is transparancy

may I ask why?  ctrader itself uses headless indicators and bots in back testing and optimisation . Would be nice if we could use this to!

There is no specific reason. Such a feature is just not implemented. Also you asked about accessing plugins and backtesting, not cBots and indicators

You’re right. Indicators and bots was related to the initial question.

I have a backgroundworker that needs to use some indicators(eg DMS) while running calculating some MTF bars.
The values of the indicators are to be used in the backgroundcalculations and the indicators should preferably be local to the static backgroundworker.
Usage like var O = Bars[10].Open;
and like
var  RS = Indicators.RelativeStrengthIndex(closePrices, entry.14);
var I DM = Indicators.DirectionalMovementSystem(entry.14);

How to achieve that without invoking the main thread?

You can't. If you need data from the Bars object, you need to work on the main thread.

Ok. Related Question. Is there a way to start a Plugin from an indicator or Cbot. Alternate: can i start  Backtesting (from plugin) in Indicator/Cbot?

PanagiotisCharalampous said: 

This method does not work on backtesting at the moment. If you need more bars for backtesting, you can start your bactesting at a previous date.

That's not a good solution you will have to change your code just for the sake of backtesting & optimizing if you use duration based calculations.

it's a bug somewhere in ctrader.automate 1.0.8
It does not write to the correct directory:

outputWindow:
1>BarneyStructureBreaks -> C:\Users\xx\Documents\cAlgo\Sources\Indicators\MyBot \MyBot \bin\Debug\net6.0\MyBot .dll
1>BarneyStructureBreaks -> C:\Users\xx\Documents\cAlgo\Sources\Indicators\MyBot \MyBot \bin\Debug\net6.0\MyBot .algo
1>MyBot -> \MyBot .algo

just  uninstall 1.0.8 (tools/nuget package manager …)
Then install 1.0.7
and your ouput wil look like:
1>BarneyStructureBreaks -> C:\Users\xx\Documents\cAlgo\Sources\Indicators\MyBot \MyBot \bin\Debug\net6.0\MyBot .dll
1>BarneyStructureBreaks -> C:\Users\xx\Documents\cAlgo\Sources\Indicators\MyBot \MyBot \bin\Debug\net6.0\MyBot .algo
1>MyBot ->  C:\Users\xx\Documents\cAlgo\Sources\Indicators\MyBot .algo

Works for me!

RE: RE:

Hi Panagiotis. Are you sure? Does that make sense?

I mean, If a sell position is triggered on BID and closes on ASK, doesn't it make more sense that the stop loss is calculated on ASK as well? Otherwise it risks setting the stop loss inside of the spread, which means the position would either be immediatelly closed if the stop loss pips is lower than the spread or it simply won't have a SL. 

I think it doesn't make sense.
Maybe spotware should add another prop called StoplossFixed that includes the spread when evaluating.
We now try to overcome this by setting the cTrader SL for shorts inclusive an ‘expected spread’ (for double safety ;-)) and checking it realtime(ontick) in the program.
I know it's not beautifull but it helps a bit.
