YPY EA Praevisionis PRO

Based on the specifics of the multicurrency architecture, the expert cannot be tested in the terminal strategy tester.

YPY EA Praevisionis PRO is a multi-currency trading robot, which uses an adaptive scalping strategy in a quiet night market before banking rollover (during the American session) based on virtual trading of synthetic instruments from various currency pairs.

Each virtual strategy uses only one synthetic order to trade at night with an average time of holding an open position is 3 hours, which ensures maximum safety of trading. The expert uses more than two hundred synthetic instruments. The EA trades all these strategies at a virtual scope, aggregating virtual orders into real orders opened on the account.

The system does not use any martingale/averaging methods.

Some constituent currency pairs always play a hedging role in a synthetic instrument. 

This EA is being constantly adjusted by the developer for short-term trading on the current market through regular updates.

The "PRO" version of the YPY EA Praevisionis robot is installed only on EURUSD M15 chart and automatically uses for multicurrency trading the following instruments: AUDJPY, AUDUSD, CHFJPY, EURCHF, EURGBP, EURJPY, EURUSD, GBPCHF, GBPJPY, GBPUSD, NZDUSD, USDCAD, USDCHF, USDJPY.

This is a new product which is distributed temporarily free until it confirms stable positive results of trading on the developer's signal monitoring.

For effective trade diversification we also recommend using an additional other trading system YPY EA Sacramentum PRO for synthetic trading in the Asian session after a bank rollover. This allows you to effectively combine these two trading systems.

Version 4.6 2019.03.19
The algorithm for detecting bank rollover time has been corrected.

All users are recommended to update the expert to the latest version.
Version 4.5 2019.03.13
Added the BrokerDST parameter in which each user needs to set the daylight saving time system used by the broker (USA or Europe)

Also, information about the control time has been added to the expert panel (Control Time, UTC 0).

This time allows the user to independently verify the correctness of the settings used for the two parameters (BrokerTimeZone and BrokerDST).

If this time coincides with the current time of UTC (Coordinated Universal Time), then the parameters of the trading system are configured to work correctly.

We remind that if all the parameters are configured by the user once correctly, then it is don't need to to adjust the time for daylight saving time and winter time (it is enough to check the relevance of the control time data in the expert panel).

For information:
The default setting (BrokerTimeZone=2) is suitable for most brokers who use the GMT +2 time offset in winter.
Also, most brokers use the American Daylight Saving Time System (BrokerDST=US)
Each user can find out this time, as well as the DST system directly from their broker.

All users are recommended to update the expert to the latest version.
