P2P order book monitoring for arbitrage
The Order Book Constructor by P2P.Army is a professional P2P order book monitor for 9 exchanges and 127 fiat currencies. Unlike the regular P2P page of an exchange, it puts two order books side by side and calculates the spread for every position — across different exchanges, assets, payment methods and order book types.
Merchants use it to find the most profitable levels for their ads, compare their prices with competitors and track specific traders. Takers use it to spot the moments when one book pays more than another costs.
Combined with amount and merchant filters and the 24-hour history of ad volume changes, the constructor replaces dozens of open browser tabs and manual calculations.

Frequently asked questions
What is the P2P Order Book Constructor?
It is a tool that shows two P2P order books side by side — from any of 9 exchanges, for any asset, payment method and order book type — and calculates the spread between positions. It covers 127 fiat currencies.
How is the spread calculated?
For every row we compare the price of the ad in order book 1 with the price of the ad in the same position of order book 2. Double-click any two ads to compare positions on different levels. If the assets differ, the price is converted through the spot exchange rate.
Is it suitable for makers?
Yes. Makers use the constructor to choose the level for their buy and sell ads, see the competitors around them and check that the spread between their two ads covers the fees.
Can I compare different crypto assets?
Yes. For example, BTC in order book 1 and USDT in order book 2: P2P.Army takes the current spot rate and shows the resulting spread, including the conversion step.
How do I know a merchant is really trading?
Open “Changes” next to the ad: you will see every change of its volume over 24 hours and whether the deal counter grew. Ads that never change are often just a showcase.
Which plan do I need?
The constructor is included in the P2P plan together with Taker Signals, SWIFT routes and International P2P. The Ultimate plan includes it as well. Order books refresh every 5 seconds and show up to 100 positions.
