Data access functions

Here are the meta-data functions :

Function name	Description	Returned value
Symbol()	Get the current Symbol of the attached chart	string
Period()	Get the current Timeframe of the attached chart	int
Ask()	Get the current Ask value	double
Bid()	Get the current Bid value	double
Spread()	Get the current Spread value	double
Digits()	Get the number of digits after the comma	double
Point()	Get the minimum value of the Symbol	double
Bars()	Get the number of bars on the attached chart	int

Here are the data access functions related to the index :

Function name	Description	Parameter	Returned value
Open(int index)	Get the Open value of the bar	index of the bar	double
High(int index)	Get the High value of the bar	index of the bar	double
Low(int index)	Get the Low value of the bar	index of the bar	double
Close(int index)	Get the Close value of the bar	index of the bar	double
Time(int index)	Get the Time (Date) value of the bar	index of the bar	DateTime
Volume(int index)	Get the Volume value of the bar	index of the bar	int

These functions are used to have the value of a specific bar related to its index.
When the index is 0, this is the last bar.
When the index is 1, this is the previous last bar.
When the index is 2, this is the previous previous last bar. And so on.

The Symbol and the Timeframe are the ones related to the attached chart.
Here are the generic data access functions, specifying the Symbol or Timeframe :

Function name	Description	Parameters	Returned value
iOpen(string Symbol, int Timeframe, int Index)	Get the Open value of the bar	The Symbol, the Timeframe, the Index	double
iHigh(string Symbol, int Timeframe, int Index)	Get the High value of the bar	index of the bar	The Symbol, the Timeframe, the Index	double
iLow(string Symbol, int Timeframe, int Index)	Get the Low value of the bar	index of the bar	The Symbol, the Timeframe, the Index	double
iClose(string Symbol, int Timeframe, int Index)	Get the Close value of the bar	index of the bar	The Symbol, the Timeframe, the Index	double
iTime(string Symbol, int Timeframe, int Index)	Get the Time (Date) value of the bar	index of the bar	The Symbol, the Timeframe, the Index	DateTime
iVolume(string Symbol, int Timeframe, int Index)	Get the Volume value of the bar	index of the bar	The Symbol, the Timeframe, the Index	int
iVolume(string Symbol, int Timeframe, int Index)	Get the Volume value of the bar	index of the bar	The Symbol, the Timeframe, the Index	int
