====== Trading Session ======

The **Trading Session** options work for ''gen.js'' and ''mm.js''.

The Trading Session options limit the time the Strategy opens new positions.
The position closing is not restricted.

We call the trading day a "session".

The options ''session_open'' and ''session_close'' set the times of day when the strategy is allowed to open positions.
We use these options in two cases:

  * to prevent entries around midnight if the broker suspends the trading due to "swap calculations".
  * to prevent high-spread entries if the broker increases the spreads near the start and end of the trading day.

The ''friday_close'' option sets when we want to stop trading at the end of the trading week.
It is a separate option because brokers have different Friday closing times depending on their time zones.

The ''trade_on_sunday'' option determines whether we trade on Sunday evening.
It is useful if the broker starts the trading on Sunday (usually around 22:00) and uses higher spreads.

The ''close_at_session_close'' and ''close_at_friday_close'' options force the strategy to close positions at the end of the trading day or at the end of the week.

These are the default options:

<code ini>
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;; Trading Session          ;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

session_open  = 00:00
session_close = 24:00
friday_close  = 24:00

trade_on_sunday = true

close_at_session_close = false
close_at_friday_close  = false
</code>

The Trading Session options work in the exported Expert Advisors in the trading and testing modes.

Set the Trading Session options in EA Studio to reproduce the same backtesting results.
We need to do it because EA Studio has the Trading Session options at the application level and does not import them from the Strategy or from an exported Expert Advisor.
