How to get the time of a price from DataSeries?
How to get the time of a price from DataSeries?
21 Jun 2016, 08:18
I get the Max Price and Min Price in specified period like following:
var period = 50; var maxPrice = MarketSeries.High.Maximum(period); var minPrice = MarketSeries.Low.Minimum(period);
Then I want to get the time of maxPrice and minPrice for the following logic:
if (maxPriceTime <= Server.Time.AddHours(-2))
{
// Do something...
}
if (minPriceTime <= Server.Time.AddHours(-2))
{
// Do something...
}
Could anyone kindly tell me how to get the price time? The price index is also OK because I can judge time by Index * TimeFrame.
Thank you very much!

RE:
Hi tmc, thank you very much, it's a perfect solution !

Hi, this method returns you how many bars back was the highest or lowest bar within a period.
private int HighestBar(DataSeries series, int period) { for (int i = 0; i <= period; i++) { if (series[series.Count - 1 - i] == series.Maximum(period)) { return i; } } return -1; } private int LowestBar(DataSeries series, int period) { for (int i = 0; i <= period; i++) { if (series[series.Count - 1 - i] == series.Minimum(period)) { return i; } } return -1; }

Hi,
Could you please explain how to invoke these methods?
How to do we say 'if HighestBar came before LowestBar'
Sorry for being such a coding novice!
Thanks in advance,
Drummond...

int x = HighestBar(series, period);
int y = HighestBar(series, period);
if (x > y)
{
do something
This is the best I have in me! It compiles fine but returns this error...
Crashed in OnTick with NullReferenceException: Object reference not set to an instance of an object.
I can't even get a print statement in the log... Normally my go to for fault finding...
If anyone can humour me it would be greatley appreciated!
Many thanks,
Drummond

Thank you Panagiotis,
Here's a simplified version of the code, still putting out the same error message.
using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;
namespace cAlgo

public class FIBBOT : Robot
{
[Parameter("TP Pips", DefaultValue = 10, MinValue = 1)]
public int takeProfitPips { get; set; }
[Parameter("StopLossPips", DefaultValue = 1, MinValue = 1)]
public int stopLossPips { get; set; }
[Parameter("Periods", DefaultValue = 20)]
public int period { get; set; }
public DataSeries series { get; set; }
string label = "Fib Bot";
protected override void OnStart()
{
}
private int HighestBar(DataSeries series, int period)
{
for (int i = 0; i <= period; i++)
{
if (series[series.Count - 1 - i] == series.Maximum(period))
{
return i;
}
}
return -1;
}
private int LowestBar(DataSeries series, int period)
{
for (int i = 0; i <= period; i++)
{
if (series[series.Count - 1 - i] == series.Minimum(period))
{
return i;
}
}
return -1;
}
protected override void OnTick()
{
int x = HighestBar(series, period);
Print(" HighestBar = " + x);
int y = LowestBar(series, period);
Print(" LowestBar = " + y);
if (x > y)
{
ExecuteMarketOrder(TradeType.Buy, Symbol, 10000, label, stopLossPips, takeProfitPips);
}
}
}
}

Hi Drummond,
The problem is that you are not initializing the series anywhere. Which series would you like to use?

Hi, this method returns you how many bars back was the highest or lowest bar within a period.
private int HighestBar(DataSeries series, int period) { for (int i = 0; i <= period; i++) { if (series[series.Count - 1 - i] == series.Maximum(period)) { return i; } } return -1; } private int LowestBar(DataSeries series, int period) { for (int i = 0; i <= period; i++) { if (series[series.Count - 1 - i] == series.Minimum(period)) { return i; } } return -1; }@Jiri
