We have received the exception and the issue will be solved in an upcoming release.
Regarding the SL issue, we would need the cBot code and backtesting parameters in order to reproduce this and explain what happens.

Hi Panagiotis,
Here is the test code that produce the SL issue, I'm using Nikkei225, Hm1 for testing
using System; using System.Collections.Generic; using System.Linq; using System.Text; using cAlgo.API; using cAlgo.API.Collections; using cAlgo.API.Indicators; using cAlgo.API.Internals;
namespace cAlgo.Robots { [Robot(AccessRights = AccessRights.FullAccess, TimeZone = TimeZones.EasternStandardTime)] public class Test2 : Robot { [Parameter(DefaultValue = 10, MinValue = 0, MaxValue = 500, Step = 10)] public int lossCut { get; set; } [Parameter(DefaultValue = 10, MinValue = 0, MaxValue = 500, Step = 10)] public int takeProfit { get; set; } double volume = 0.0; protected override void OnStart() { // To learn more about cTrader Automate visit our Help Center: // https://help.ctrader.com/ctrader-automate }
Can you also tell me the broker? This usually happens when your SL falls within the symbol's spread. Please check if this is the case
Hi there,
You can use Positions.Opened event and check if the stop loss was set. If the stop loss is null you can act accordingly i.e. place it at a valid distance.

I want not to submit an order if the StopLoss price is invalid.
so, I wrote a if check statement like below but my order is still without SL (empty SL). Why?
if (stopLossPrice < Symbol.Ask - Symbol.Spread) // Check if stop loss is valid ExecuteMarketOrder(TradeType.Buy, Symbol.Name, volume, "Test", StopLossPips, TakeProfitPips, stopLossPrice.ToString());

This happens because you only assign values to indicator data series, when the index of each higher timeframe changes. Hence for the rest of the array elements the value stays NaN. The solution to this depends on what you want to achieve. For example, why do you
Thank you for your reply. I want to test my GMMA strategy with multi-timeframe.
My cBot staretegy is 1hour resolution and should be able to access to the above custom indicator(multi-timeframe GMMA)'s TimeFrame.Hour4 Last(n) values.
Can you me an example on how to code this correctly?
Hi there,
I am sorry but I cannot write the code for you. If you have specific questions, I am happy to answer them. At the moment I do not see a reason to leave the data series values to NaN.

Hello Panagiotis,
What do you mean by “At the moment I do not see a reason to leave the data series values to NaN.” ?
I made some mistakes in my code?
Can you share the cBot code as well so that I can tell you exactly where the problem is?

Hi there,
Here is a visualization of your problem using the debugger
Your Indicator data series have NaN values because you do not assign anything to them when the time does not match the higher timeframe time. Hence the problems in your logic.
I do not understand why you have created a separate indicator for this and have to manage all this complexity. You could just initialize the moving averages inside your cBot and use them.

Panagiotis
Hi Panagiotis,
Thank you for the screenshot. I see the problem now.
I changed my cBot code as following and it seems to print higher time frame values correctly.
However, how can I display, for example, this _longEma2 onto my bachtest chart?

I tried with Spotware cTrader cross broker cTrader and it generates a similar error message.
Error | Failed to get symbol 'USDJPY' quotes: Symbol USDJPY has no quotes at 2003/07/01 4:00:00.I think this is because my Csv data is going all the way back to year of 2003 while the broker's USDJPY's first data is some where 2011.
How we can deal situation like this?
