Hi firemyst,
Because this part of the code was not executed. The indicator is initialized only after it has been added on the chart. If you need the parameter to show a value, you need to put a default value.
Best Regards,
Panagiotis
I'm confused@Panagiotis, because I do add it to the chart as I said in the comments in the code. Let me repeat them here:
//Unexpected behavior in cTrader?
//Add this indicator to any chart.
//Leave the parameter blank. It should "set" the value to "Hello" in the Initialize method.
//Call up the parameter window again for this indicator
//the value "Hello" isn't displayed even though it has been set.
//Why not?
After it's added to the chart, if you call up the indicator to view the properties, it's blank.
Hence why the cTrader window says, "Modify indicator" instead of "Add indicator" (when it's first being addedto the chart).

@Panagiotis / Spotware:
Does this answer still hold true?
I want to retrieve historical spread data in indicator and bot code, and I can't seem to find a way to get historical spread values, or (at the very least) historical bid/ask prices on each historical candle close
Is there a way to do this?
Thank you.
Hi firemyst,
To find the historical spread just check the difference the historical bid/ask prices when running backtesting using tick data.
Best Regards,
Panagiotis
Sorry for the confusion -- I meant is it possible to get this data programmatically? Eg, in cbot code what can I do to get the historical data in real time if it's possible? For example, if I'm on the H1 timeframe, and currently at the 11am candle, if I want to obtain the spread in the cbot code at the close of the 8am candle, how would I do it?
Thank you.

RE: RE: precision if stopLoss or takeProfit is specified in pips

Hi FireMyst,
Backtesting is a simulation of the trading on your machine. It does not communicate with the server and it does not account for all possible parameretes of a cBot's runtime. The specific error is sent by the server where the checks are a bit more strict. I would advise you to test your cBots on a demo account as well before moving to a live trading account.

Hi Panagiotis,
I saw for most Symbols the precision for stopLoss or takeProfit specified in pips is 1 digit. But for e.g. XAUUSD it is 0 digits.
Is there a way to find out programatically what the precision is?
Kind Regards,
Thomas

As far as I know it is the close price which is considering only the bid price.

Any chance your team is going to include this popular indicator in an upcoming release of cTrader?

Hi firemyst,
I have checked this is the past and it seems to be an issue with the way the values are calculated for each bar in the real time and what happens when some ticks are missed. I haven't tried to solve it but I would try to recalculate the value of each closed bar when the bar changes and the OHLC data for the previous bar is finalized.
Best Regards,
Panagiotis
Thanks @Panagiotis.
That gives me a good starting point.

Hi firemyst,
Supertrend is a custom indicator and if you are using the one available in the forum, it has a lot of defects. This is one of them.
Best Regards,

If I post the code would you be able to have a quick look and see what the problem is? I'd like to know how I can alter the code to overcome this defect. Or at least what's causing it and why it happens.

Out of curiosity, did you ever receive a response? I don't see any in this thread, but that's not to say they didn't message you separately. I know a few people in the USA who would like to use cTrader.
Thanks :-)

HI @Panagiotis:
Thank you for the updates. I think you need to at least update thread 22129 then to indicate to everyone it has been resolved :-)
As for Telegram - we have the forums - how hard is it to create a separate forum and/or a read-only thread and include the updates there? Users should not have to download another application and join yet another Spotware group in that application to now find out the latest updates.
Or is Spotware going to put a Directory on their website that tells users what they should do and where they should go to get certain information?
- Spotware.com -> product information, sales information, download actual products
- Facebook -> latest sales/marketing promotions
- cTrader.com -> forums and latest API announcements
- Telegram -> latest change release logs
etc etc etc.
Getting a bit ridiculous don't you think?
How many 3rd party applications, services, and systems does Spotware want us to sign up to in order to use and get information on their products?

Hi alphabet_asa,
PipValue will give you the value of a pip in your account's currency. If your account currency is the same with the quote currency then PipValue and PipSize will match.
Best Regards,
Panagiotis
Thank you for the reply! If that's the case then how do I get the currency's exchange rate?
HI @alphabet_asa:
Unless I'm missing something, isn't that what the Forex quote (Symbol.Bid, Symbol.Ask) is showing?
For example, if you're looking at the AUDUSD forex pair, and the price quoted is 0.68, then the exchange rate is 1 AUD = $0.68 USD.
Similarly, if you're looking at USDAUD, and the price quoted is $1.46, then the exchange rate is 1 USD = $1.46 AUD.
If you're looking at a foreign market index, then lookup the forex pair of your currency vs that index's currency. Thus, if you're trading the US Dow (US30), and your local currency is New Zealand Dollars, then get the symbol price for either USDNZD or NZDUSD, following the examples above depending on which currency is listed first in the forex pair.

I know I suggested and provided this feedback to Spotware a while ago too. Every other charting package allows the user to set different colors for indicators to show whether their values are increasing or decreasing. For whatever reason, Spotware hasn't implemented this basic feature. So until then, it's left to you as the user to either develop your own indicator which does it, or find indicators that have the option.

RE:
PanagiotisCharalampous said:
Hi FireMyst,
Yes please, if you can record a video it would be helpful.
Best Regards,
Panagiotis
I've figured out how to reproduce it one way.
1) Create an indicator where Overlay = false
2) Load it onto a chart in cTrader and set a Level property of 0 to color yellow.
3) Save the chart as a template
4) load the indicator's source code in Visual Studio
5) make some changes to it.
6) Save and recompile the indicator
7) Load up cTrader
8) The Level 0 line on the indicator will probably be gone
9) reload the template
10) the line reappears
11) close and reopen cTrader. The line disappears again.
12) reload the template to have the line reappear
13) change the visual studio code and recompile the indicator
14) the Level 0 line will reset and disappear again.
15) reload the template
16) close cTrader
17) reopen cTrader and the line is gone again.
18) delete the indicator.
19) reapply the indicator to the chart and change the level 0 line to yellow.
20) save the template.
21) close/reopen cTrader.
Now the line will stay on the chart until the code is updated again. At that point, the settings for the Level lines do not stay.
Hope this helps.

Hi FireMyst,
Shouldn't it be flipped when the close price passes through and not the high/low?
Best Regards,
Panagiotis
Yes. And the CLOSE did pass through it. When a candle is open, the close is the current price until the actual candle closes. I believe that's what the cbot frame returns with MarketSeries.Close.Last(0) for every OnTick.
Thus when the price went down through the PSAR to form the low, the close would have passed the PSAR, and should have flipped it.
Here's an example from another broker's platform:
