History Center on Tools Menu on MT4 Platform

The history center in MT4 is located on the tools menu. The history center will begin to store data for each chart that you open on the MT4, This means that if you open the Oil Trading M15 chart, then from that point on the MT4 history center will store information for this Oil Trading time frame and every time you login again to the platform to trade this information will be updated with the most recent prices & will then stored.

This also means that for any other chart not opened on your MT4 the platform will not start to save data for that chart. For example if you only open M15 for Trading only information for M15 will be stored, and not for Trading 1H or Oil 4 Hour chart. Therefore, if you want to begin saving records for 1 H & H4, then you must start by opening these time frames & the data will start to get saved from this point.

In the example shown below, the Oil Trading Time frames are Shown, However only M15, H1 & H4 Icons are marked yellow and Green meaning data is being saved and updated to the History center. All the others are Gray in color, meaning they haven't yet been opened on this platform. To change this & have these charts begin to update and have the price info saved, just open any time frame for the Oil, for example the 30 minutes and the Icon for this time frame will immediately change from Gray to Yellow and Green, do the same for all the others.

From the above example you can see the format that MT4 uses to store price data info as figures, these figures are the ones used to replicate the trading chart.

Why Use The MT4 History Center

Because of the format of storing data in figures it means that these figures can be analyzed using mathematical formulas and mathematical methods can then be used to trade the prices by analyzing this price movements.

These Mathematical methods are implemented for trading using computera lgorithm programs. Computer programs will be programmed using these mathematical techniques and formulas. This will produce what in coding is known as algorithm, these algorithms are implemented in MetaTrader 4 using programs known as EAs - Automated Oil Programs.

This Expert Advisors answer the question why the need for the History center? The information stored is used by crude traders to test their automated Oil Expert-Advisors to get an idea of how these EA Oil Robots would have traded & then determine whether they are profitable or not. If these are profitable, traders implement these automated systems on the real market, if not then the trader changes their mathematical formula & reprograms the algorithm, then tests this new algorithm with the same data on the history center until the time the trader will program an algorithm that's profitable enough to trade the live market & make profitable trades.

One of the methods of obtaining data to the history center is to download this information using the download button key as shown and illustrated below: However, this downloaded figures tends to have gaps & give inaccurate info, therefore as a trader it's best to use data that has been downloaded by platform itself after installing it. That means the information that is available from when you downloaded the platform and started to trade with it, even if it's a few weeks or a few months.

If you want to start testing these EAs then for every oil instrument you trade you must open that oil instrument, as well as opening all the time frames of that oil instrument, that's the following:

1. 1 Min - M1
2. 5 Min - M5
3. 15 Min - M15
4. 30 Min - M30
5. 1 H - H1
6. 4 Hours - H4
7. Daily - D1
8. Weekly - W1
9. Monthly - MN

When it comes to testing your Expert Advisor, select the begin date as the date when you'll execute the above operation of downloading all the data for these chart time frames and for different MT4 symbols also, so as to make sure your Expert Advisors are using correct data and give you the right results.

Because of this reason you shouldn't download any data on your MT4, just use the data that's available after you open the charts as displayed above & begin from that point onwards.
