An example of receiving the High and Low prices of bars over the past 24 hours.
Hot Keys:
- The "H" key (case insensitive) — find the High price
- The "L" key (case insensitive) — find the Low price
To get the High and Low prices, the third form of call CopyHigh and CopyLow is used:
Requesting based on the first and last date of the required time interval:
int CopyHigh(
string symbol_name, // Symbol name
ENUM_TIMEFRAMES timeframe, // Period
datetime start_time, // Start date
datetime stop_time, // End date
double high_array[] // Array to copy High prices
);
string symbol_name, // Symbol name
ENUM_TIMEFRAMES timeframe, // Period
datetime start_time, // Start date
datetime stop_time, // End date
double high_array[] // Array to copy High prices
);
Requesting based on the first and last date of the required time interval:
int CopyLow(
string symbol_name, // Symbol name
ENUM_TIMEFRAMES timeframe, // Period
datetime start_time, // Start date
datetime stop_time, // End date
double low_array[] // Array to copy Low prices
);
string symbol_name, // Symbol name
ENUM_TIMEFRAMES timeframe, // Period
datetime start_time, // Start date
datetime stop_time, // End date
double low_array[] // Array to copy Low prices
);
The time interval is represented as follows:
datetime stop_time = TimeCurrent(); // stop date and time
datetime start_time = stop_time-24*60*60; // start date and time
datetime start_time = stop_time-24*60*60; // start date and time
start_time <-> stop_time
Visualization:
For convenience, text information is displayed on the chart (the example with low prices):
Also a vertical line is displayed in the chart (it shows the left border of the time interval), and a horizontal line is shown (means the searched price) — (the example with low prices):
