N-Second Chart Creator EA

Hi Math.

Thanks for the EA. Today I noticed that it doesn't process missed ticks and as a result High/Low of the written bar are stored incorrectly if the new High/Low occurred on such a missed tick. As there are countless ticks per minute which are not sent by the broker (aka missed ticks) the issue occures quite often. Especially new Highs/Lows often consist of just a single tick. Many times High/Low of the bar is updated immediately but the tick itself is not sent by the broker.

A very simple example for a bullish bar with the High on a missed tick:
Tick 1: 1.2500'0 - bar state: 0/0/0/0 (meant as shortcut for O/H/L/C, only the last digit noted)
Tick 2: 1.2500'2 - bar state: 0/2/0/2
Tick 3: 1.2500'4 - bar state: 0/4/0/4
Tick 4: 1.2500'5 - bar state: 0/5/0/5 - if this tick is missed/not sent by the broker the stored High of the recorded bar will still show 4
Tick 5: 1.2500'4 - bar state: 0/5/0/4
Tick 6: 1.2500'3 - bar state: 0/5/0/3

So with tick 4 missing the stored second bar looks like 0/4/0/3 while the M1 bar correctly shows 5 as the High.

How to fix this: You should not only process the arrived tick as new Close but also monitor High/Low of the corresponding M1 bar. If the M1 bar makes a new High/Low during the building time of the second-bar and the new H/L is not reflected in the tick price itself then you know you missed a tick and should update H/L of the current Second-bar.

Why is this an issue: Because regular candles of the regular timeframes make new High/Lows but there are cases where your Second-chart doesn't.

Did I explain this in an understandable way? I could elaborate more and post screenshots of examples and the data in the HST files if you wish so. But I think the issue is easy to grasp and just writing it up like I did would be enough (and saves me some time). :-)

What's your opinion? Thank you

ps: Is it possible to store the seconds in the .HST file? You only store full minutes so all bars of a minute have the same timestamp. See the attached screenshot. It shows 4sec-bars of the Russel. All bars of a minute have the same timestamp but they should have different ones, each one with a shift of 4 sec. to the precessor.

Hi emmzett,

Thanks for reporting your observation. As you have noticed, the EA algorithm has been written with the essential assumption of receiving all the ticks live. When one or more ticks are missing from the broker's server, there is no mechanism to detect and react to such scenarios at the current version of the EA. However, as you suggested for the extreme cases, which are High and Low of the M1 bars, it seems that we might be able to detect and correct it. I will consider this in my backlog of tasks to implement in the next versions.

Hi MT7 I was just wondering if there is any way to access the 1 second chart. I see after downloading it only goes to 3 seconds. Is there a reason this is the case. Thanks very much.

Hi,
Below 3 seconds, according to my experience, is not reliable. Such charts shall be created by the broker (and needs support by the platform, as well).

Ah I see, thanks for the reply man.

It's a separate custom symbol. If you want to trade from that chart you need custom buttons that trade the main symbol.
History bars are made by copying ticks and altering their times. The rest are MT5 built-in functions.

Is it possible to have multiple seconds chart generated from the same M1 chart, like adding option in inputs maybe 3, 4 different timeframes.
Example, I open one M1 timeframe activate the EA and in input add 5sec, 15sec, 30sec as input and get 3 offline charts one for each

This way people including me who need multiple timeframes can avoid laging of PC due to lots of processing needed when you have multiple charts to solve the same problem.

Hi MathTrader...big fan of your work...i find that the 20 seconds chart is a beautiful tool for me ....only issue I have is that it does not have the ability to handle MTF indicators ..take for instance the Mtf moving average I use....is there a way the indicator can be updated to allow mtf indicators to be used accurately on it?... it'd be super nice....thanks

What MTF indicators are you interested in? Many of them work...

For example, a MTF moving average... different values emulated from the M1 timeframe on the 5 second chart .

Hi,

Unfortunately it is not possible to use the existing MTF indicators as MT4 platform doesn't support chart timeframes less than M1.

P.S. only possible by programming some special MTF indicator that is aware of seconds charts...

Hey Maths, How much for mql4 file?

Hi math...thanks for the response.....i understood what you wrote and it makes perfect sense....

is there a way to make this happen "only possible by programming some special MTF indicator that is aware of seconds charts" maybe a 1-minute MA...

it'd be very nice.

Sorry, but I don't understand this problem.
In MT4, a number of indicators work correctly on the offline chart (unfortunately, not all).
You have to try different.
If you don't find it, you can emulate an approximate indication by adjusting the parameters of the built-in default indicators.
An old Polish saying says: "Necessity is the mother of invention"...

What exactly are you looking for?

EA no longer working as of MT4 Build 1420.
Please recompile into the new working standard!

Hi, for n-Seconds Bars you can try this:

https://www.fxblue.com/appstore/12/tick-charts-mt4

It works properly.
Unfortunately, it requires registration.

It also allows you to emulate
Range Bars, Renko and Ticks charts. And also unusual for MT4 M2, M3, H2 charts and others you can imagine.
