Definition of the information addressed on the article:

To evaluate the importance of real-time track the article discussion is by the current track of the USD/RUB at night time.
The discussion's subjective is the real-time pricing of USD/RUB and it does not include the aspects of any other effects on the pair.
Dukascopy real-time pricing data is as an indicator of any other bank that do not have or not publishing the price at real-time.

Introduction
The importance of the real-time data of currencies and their value is in-order the currency will never be under-valued or to be over-valued. It is when the seller and the buyer agree upon the values on the exchange rate given at any time and there is no blurred and none defined information to make the fair trade.
What is happening with USD/RUB is that it has no night time pricing data. To have the missing trading information, if such real-time track is an issue and the fair trade missing the correct values,the article include the change of the real-time dataand the present data information of the trading.

The main question that is addressed in the article , the missing price-data at night time can that lead to under-valued Ruble cost.


Historical Change of the Real-Time price data:
After check-on the USD/RUB pair. The founding is that since start of year 2013 01 January the USD/RUB has no longer night time real-time price data. As shown on the graph below the change is clearly seen on the real-time data availability.
Prior 2013 there is night time prices while starting 2013 there is no data.


Run-Through the graph analysis show that since start of the year 2013 there was no real-time pricing at night time up to today.


Present price-data
August's 2015, as sample from the last years of USD/RUB, show that 11 days against 5 day the Rubble start from a lower value after the night.


Logical view indicates the price of Ruble is lost during the night time when there are no real-time pricing-data. The logical-view as meaning is the fact that during the day the RUB shows strength while at night the RUB is sold at weaker value as of the risk taken by the seller to sell at closed market of the pair and almost always the day starts from the Rubble was sold at weaker value.
As well, August of 2013 show that almost each day the Rubble start from a lower valued.



Conclusion

Not existing Real-Time price data can lead to aggregated weakness of the currency and there is a risk for fair trading. .
Aggregation toward currency weakness happens when every day there is some percentage of weakness after night time of the Rubble that during the day that weakness is not balanced toward the strength side.

It is when the morning price state at what value the currency was sold and bought at night. Means the seller always take risk-free percentage of 30% to each side from the average price and not the basic plus fee of around at most 5% like might would have with real-time data being available to the seller and the buyer.
Also, the currency is not traded by it's stronger price points as there is no indication the price has changed since the market has closed. The good side for the Rubble is not in-effect as the trading price remains by end of the day price.
A real life example of bank's currency exchange point at Airports is a specific trade when the currency bought is always losing it's value but by how much the sold currency can be under-valued.
In-case the real-time data continue to be partial during the business days of the week that could lead to inflation because of abandonment of market track. To balance such differences can, the manufacture's sale scheme Resale Price Maintenance that state to the seller the lowest and/or highest price that can be set on the products of the specific order, keep the currency safe at its origin's value. In order to put the Resale Price Maintenance into the banking currency trading. It is “ products of the specific order” re-defined to the amount and at what prices the purchasing bank being the retailer bought the currency and that specific amount can not be sold out of the contract's price range. Of-course, what could be more happening is that the seller could be left out of “stock” of cash as not enough per-bought. Whereas the origin price is preserved and end-user get the correctly value paper.


A logical question remains:
How can a safe be safe while at night time no one is guarding it?
That is impossible and to keep the safe to be safe it is to have track of it at all time.
