You can try this indicator: https://ctrader.com/algos/indicators/show/2855/

It allows you to save all your chart drawings into a file and then you can load it later back.

Hi amusleh, 

Where can the heartbeat documentation or a usage example for Open API be found?

Looking forward to hearing back from you, 
Best Regards, 

Hi,

Please read the documentation connection tutorial.

Hi amusleh,

The connection tutorial link https://spotware.github.io/open-api-docs/connection/ is broken. Could you please share again.
I'm having issue sending the heartbeat request using the python sdk.

Thanks in advance.

Hi,

With the above approach there can be positive or negative pips at target (take profit). The same can be done through CTrader gui.

How to approach the same?

 

Hi,

Not sure what do you mean by positive / negative Pips, you can create the same cTrader advanced take profit functionality inside your cBot.

Check the number of Positions Pips on each OnTick, if it reached X pips close X% of it's volume, and record the position on a collection like a List.

It all depends on your coding skill.

But in 4.1 it was not the behaviour what changed

Yes, this is a behavior change, we are not going to change it back to 4.1 behavior as it's not possible.

Let me know how this can be achieved with FORM or without FORM

We are going to add dialog and window to the API that mimics the looks of cTrader and uses current controls, then you don't have to use WinForms or WPF.

Is there a way to move a button within the child window

Hi,

You just have to iterate over a data series points with a loop and find the minimum or maximum values.

DateSeries itself has minimum and maximum extension methods: 

Minimum Method - cTrader Automate API

Maximum Method - cTrader Automate API

You can also use a for loop or Linq.

Hi, thank you, but I didn't mean that. I want to get it more precisely
And I don't want to get the maximum of ten previous candlesticks, for example, I just want to get the highest previous and the highest two previous ones
For example, I want to say that if the last value of RSI exceeds the previous highest point, open a buy position.
I hope you understand what I mean

Hi,

You can use the DataSeries Maximum / Minimum methods for that, just use Maximum to find the highest value of RSI on x previous bars, then compare it with current RSI value.

You can't break a position, but you can check if the position profit reached x pips and then close x% of it's volume.

Hi,

If you open a the window from a detached chart then it will appear behind the chart, if you open the window from an attached chart then it will appear over cTrader main window.

As your indicator / cBot runs from their own process it doesn't know about the cTrader windows so it's not possible for us to change this behavior.

Hi,

So you are trying to calculate the Pips for positions that are partially closed or added?

If that's what you are looking to do then you can't, because the API doesn't give you the data for partially closed / added positions.

When you close part of a position or add more volume to it the history is not updated until you close the whole position, nor the positions closed / opened events are triggered.

 

 

 

But there's obviously some mathematical formula that's used because cTrader does it.

As I mentioned in my original post, I keep track of each position's volume and entry price that are added (eg, I have my own history), so I should be able to do it before the position is closed just like cTrader.

So, can't you look at cTrader's source code and tell me what formula it's using to do its live calculation? :-)

Thank you.

 

Hi,

The cTrader Pips column shows the different in Pips between position entry price and current price.

If you add new volume to the position then the entry price of position will change, and for Pips it will use the new entry price.

That's how it's calculated on cTrader, so for:

What I mean by overall pips is if my positions are:

1) 10000 units of EURCAD @ 1.3547

2) 1000 units of EURCAD @ 1.3562

3) 1000 units of EURCAD @ 1.36701

and price is currently at 1.35835

cTrader will use 1.36701 as entry price and 1.35835 as current price, the difference will be position Pips, it doesn't take into account the previous entry prices.

Hi,

Can you tell me which column you are talking about? I can't find any overall Pips column in cTrader.

The "Pips" column as per the "Positions" and "History" tabs:

Thank you.

Hi,

The method I posted will give you the same value that you see on Pips columns with some fraction error due to rounding or delay.

There is no overall Pips, each position Pips is separate and it's not related to other positions.

Hi,

10 is the maximum number of winning trades on a row combined long and short.

12 is the number of consecutive winning trades if you only consider long trades, so in between those 12 trades there were some losing short trades.

That's how it's calculated, the values are valid.

Hi,

I just tested WinForms top most and it worked fine, I had several child windows and the WinForms window were over all of them.

The only issue I noticed was with file dialogs, they appear on the back of cTrader main window.

Check here: WinForms - cTrader Automate API

You can try the last WinForms sample and set it's top most to True before ShowDialog call.

And please post a full sample cBot code that can reproduce the issue.

The first request you send to server should be application authentication request not account auth request.

You can find the guide at: Connection - cTrader Open API
