OrderBook History Library

3

Order Book, known also as Market Book, market depth, Level 2, - is a dynamically updated table with current volumes of orders to buy and to sell specific financial instument at price levels near Bid and Ask.

MetaTrader 5 provides the means for receiving market book from your broker, but in real time only, without access to its history. The library OrderBook History Library reads market book state in the past from archive files, created by OrderBook Recorder. The library can be embedded into your indicators and expert advisers (source codes are required), and then they can be tested with the market book data in the tester.

In particular, the library is used in the indicator OrderBook Cumulative Indicator and demo expert adviser OrderBook History Playback.

Here is an example of the header file for including the library into your MQL program:

input string OrderBook_FileFolder = "Books";
input bool OrderBook_UseCommonFiles = false;
input int OrderBook_TimeZoneCorrection = 0;

typedef void (*pOnBookEvent)(const string &symbol);

#import "OrderBook.ex5"
void OrderBook_Init(pOnBookEvent ptr, const string folder, const bool common, const int offset);
bool OrderBook_MarketBookAdd(string symbol);
bool OrderBook_MarketBookRelease(string symbol);
bool OrderBook_MarketBookGet(string symbol, MqlBookInfo &bookArray[]);
long OrderBook_MarketBookPeek(string symbol, MqlBookInfo &bookArray[]);
void OrderBook_OnTick();
void OrderBook_OnTimer();
bool OrderBook_CheckForEvents(datetime current);
#import

#ifdef ORDERBOOK_SUBSTITUTE
#define MarketBookAdd OrderBook_MarketBookAdd
#define MarketBookRelease OrderBook_MarketBookRelease
#define MarketBookGet OrderBook_MarketBookGet
#endif

The input parameters are defined for convenience - they should be passed into the function OrderBook_Init.

  • OrderBook_FileFolder - a name of the root folder, where subfolders and files of the market books are stored; by default - "Books"; every subfolder is named according to specific work symbol; for example, the ticker GAZP will form the files MQL5/Files/Books/GAZP/*.hob;
  • OrderBook_UseCommonFiles - an option for reading files from the data folder of the current terminal (false, by default) or from the common data folder for all terminals (true);
  • OrderBook_TimeZoneCorrection - a correction of date and time, which is required in case, that archives are read in a terminal with a timezone, which differs from a timezone of the terminal where the archives were created; specified in seconds; for example, if the market book was saved with the server time in GMT+3, and then it's applied on quotes from a server, where time is in GMT+2, the correction should be 1 hour (-3600 seconds), because times in GMT+2 go 1 hour late in comparison to (i.e. they are 1 hour smaller than) GMT+3; 15:00 in GMT+3 is 14:00 in GMT+2;

Functions

  • OrderBook_Init - initialization of the library, should be called from OnInit; the first parameter should be the event handler OnBookEvent;
  • OrderBook_MarketBookAdd, OrderBook_MarketBookRelease, OrderBook_MarketBookGet - analogous functions to corresponding standard MQL functions; while working online, the standard functions are called internally - this way, emdedding the library will not alter the source code logic; while working in the tester, the library retrieves data from the files; the subscription for market book for current chart's symbol only is allowed;
  • OrderBook_MarketBookPeek - similar to OrderBook_MarketBookGet, but always reading data from files - both in the tester and online; MarketBookGet is never called;
  • OrderBook_OnTick - optional execution of the library for latest tick from OnTick; only for the tester, online does nothing;
  • OrderBook_OnTimer - optional execution of the library for latest known time from OnTimer; only for the tester, online does nothing;
  • OrderBook_CheckForEvents - optional execution of the library from the tester and online, ad hoc - for specified date and time;

Adding the line #define ORDERBOOK_SUBSTITUTE into the source code before including the header file will implicitly replace all calls of the standard market book function with corresponding library's functions.

MetaCOT 2 CFTC ToolBox is a special library that provides access to CFTC (U.S. Commodity Futures Trading Commission) reports straight from the MetaTrader terminal. The library includes all indicators that are based on these reports. With this library you do not need to purchase each MetaCOT indicator separately. Instead, you can obtain a single set of all 34 indicators including additional indicators that are not available as separate versions. The library supports all types of reports, and prov
This is a simplified and effective version of the library for walk forward analysis of trading experts. It collects data about the expert's trade during the optimization process in the MetaTrader tester and stores them in intermediate files in the "MQL5\Files" directory. Then it uses these files to automatically build a cluster walk forward report and rolling walk forward reports that refine it (all of them in one HTML file).

This non-trading expert utilizes so called custom symbols feature ( available in MQL API as well) to build renko charts based on history of real ticks of selected standard symbol. RenkoFromRealTicks generates custom symbol quotes, thus you may open many charts to apply different EAs and indicators to the renko. It also transmits real ticks to update renko charts in real time. The generated renko chart uses M1 timeframe. It makes no sense to switch the renko chart to a timeframe other than M1. T

Most of traders use resistance and support levels for trading, and many people draw these levels as lines that go through extremums on a chart. When someone does this manually, he normally does this his own way, and every trader finds different lines as important. How can one be sure that his vision is correct?

Mirror

It uses the idea that the price fluctuations consist of "action" and "reaction" phases, and the "reaction" is comparable and similar to the "action", so mirroring can be used to predict it. The indicator has three parameters: predict - the number of bars for prediction (24 by default); depth - the number of past bars that will be used as mirror points; for all depth mirroring points an MA is calculated and drawn on the ch

Versión 1.4 2021.10.19
Support for multiple symbols is added. You can now enable monitoring of many different symbols (just call OrderBook_MarketBookAdd for them) and then receive market book events from corresponding history files (they should be stored by the recorder running on charts with these symbols). Don't forget to check symbol parameter in OnBookEvent handler.

New function is added to get open interest of specific symbol: bool OrderBook_SessionInfoSymbol(string symbol, double &openInterest, double &buysVolume, double &sellsVolume).
Versión 1.3 2020.05.09
New hob-file format 1.2 is added. In this format, 3 values of current session volumes are saved along with every book: SYMBOL_SESSION_INTEREST, SYMBOL_SESSION_BUY_ORDERS_VOLUME, SYMBOL_SESSION_SELL_ORDERS_VOLUME.

It's not necessary to convert all historical hob-files to format 1.2, both formats are supported in parallel.

New function OrderBook_SessionInfo(double &openInterest, double &buysVolume, double &sellsVolume) is added to get total current volumes, saved along with current book.
Versión 1.2 2019.09.19
The library is recompiled in a newer build because MetaQuotes introduced another change to their compiler, which broke back-compatibility of exports/imports (exported functions with typedef-ed parameters compiled in older builds can not be imported since build 2085 or so).
Versión 1.1 2019.04.20
Starting from build 1930 MetaQuotes broke MQL5 back compatibility with MqlBookInfo structure by adding new field volume_real into it.

This version of the product supports new structure format, but it will not work on older builds.
