Hello again amusleh,
Further to my query earlier today please ignore it. I've actually got closer to working in out for myself. thank you anyway.
May be one general question please. with the trading panel can we make it Interactive instead of static. (like IsInteractive = true?)
thank you

Hello amusleh,
You helped resolve a query with ComboBox's not so long ago, (found here https://ctrader.com/forum/calgo-support/40141) and I was hoping you may be able to help me too. I've been trying to add a this ComboBox to the SampleTradePanel for some time now but unfortunately have not been able to work it out.
Are you able to help me with a sample code showing how to add this combobox to the SampleTradingPanel. If we just replaced the “close all button” with this ComboBox please.
Below is the code from the SampleTradePanel
Any assistance would be greatly appreciated. Thank you

Hi MongolTrader,
Instead of passing a Robot object to the Init() method, try passing a TestMulti object.

Hello Panagiotis,
Thank you for this. It is newbee here.
I've been trying to do what you suggested since you sent me this answer but unfortunately to no avail. I simply don't know how to do that. Can you please give me a sample of how to pass a TestMulti object.
Thank you again.

RE: Multi Symbol cbot & Paramaters
Hello Panagiotis,
Attached below is a sample of a multi symbol cbot I found which I believe was at (downhttps://ctrader.com/forum/calgo-support/22633) however, this link is no longer available.
It is excellent and I have been adding to this code however I am stuck when adding a Parameters as I can't get it to read the parameter. For example:
Say I wanted to add a Parameter for the "Periods" that will be used for the RSI indicator (which is sitting in the "public void init(Robot bot, string symbol)")
[Parameter("RSI Period", DefaultValue = 14)]
public int period { get; set; }
Or another example would be a parameter to set a "Max Number" of trades & pass this through to "void OnBarOpened(BarOpenedEventArgs obj)" section
[Parameter("Max Open Trades", DefaultValue = 10)]
public double MaxPositionsAllowedPerSymbol { get; set; }
When I do, for some reason they simply aren't available to utilize or pass through to the RSI indicator sitting in the "public void init(Robot bot, string symbol)" etc.
I know I'm missing something, but I just can't seem to find what that is. I've been trying for weeks. Any assistance sample would be greatly appreciated.
Thank you!
Code sample below
using System;
using System.Linq;
using System.Collections.Generic;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;
namespace cAlgo.Robots
{

public class TestMulti : Robot
{
// Multi symbol bot test
string[] symbols =
{
"AUDCAD",
"AUDCHF",
"EURUSD",
"CHFJPY"
"EURUSD",
};
List<RSI_Strategy> strategies = new List<RSI_Strategy>();
protected override void OnStart()
{
foreach (var sym in symbols)
{
var rsiStrategy = new RSI_Strategy();
rsiStrategy.init(this, sym);
strategies.Add(rsiStrategy);
}
}
}
// Sell when RSI crosses above 70
public class RSI_Strategy
{
RelativeStrengthIndex rsi;
Robot bot;
string symbol;
public void init(Robot bot, string symbol)
{
this.symbol = symbol;
this.bot = bot;
Bars bars = bot.MarketData.GetBars(bot.TimeFrame, symbol);
rsi = bot.Indicators.RelativeStrengthIndex(bars.ClosePrices, 14);
bars.BarOpened += OnBarOpened;
}
void OnBarOpened(BarOpenedEventArgs obj)
{
if (rsi.Result.Last(1) > 70 && rsi.Result.Last(2) <= 70)
{
bot.ExecuteMarketOrder(TradeType.Sell, symbol, 10000, symbol, 10.0, 10.0);
}
if (rsi.Result.Last(1) < 30 && rsi.Result.Last(2) >= 30)
{
bot.ExecuteMarketOrder(TradeType.Buy, symbol, 10000, symbol, 10.0, 10.0);

amusleh said:
Hi,
No, you can't get the angle from API, but you can calculate it if you want to:
private double GetAngle(ChartTrendLine trendLine) { var x1 = Bars.OpenTimes.GetIndexByTime(trendLine.Time1); var x2= Bars.OpenTimes.GetIndexByTime(trendLine.Time2); double xDiff = x2 - x1; var yDiff = trendLine.Y2 - trendLine.Y1; return Math.Atan2(yDiff, xDiff) * 180.0 / Math.PI; }The above method will return the angle of a trend line in Degree, it will not work properly if your trend line is drawn in future time, because it uses bar indices for x axis.
If you to get the angle from API then please open a thread on forum suggestions section.

Back testing
Hello, I've struck a situation in calgo while back testing and am hoping someone can assist or point me in the right direction.
My cbot includes a parameter for trading hours. (ie Start Hour & Stop Hour - - eg Trade between 8pm & 10pm etc)
When the back testing is complete, in the results it seems that there are trades with an entry time outside the selected time parameter, in this case between Start hour 19 & stop hour 21.(or 7pm to 9pm)
One would expect to only see trades with an entry time between the filtered start & stop times. Is this correct or am I missing something?
Any assistance would be appreciated
Thank you
