GerFX QuantFlow Scalper 外汇EA

Before you buy a night scalper please be aware of the risks involved:

1. Past performance is no guarantee of future profitability (the EA could also make losses). 
2. The backtests shown (e.g. in screenshots) are highly optimized to find the best parameters but therefore do not give a realistic prediction of future profitability.
3. Any mean reversion can get caught on the wrong side of a fast movements due to unexpected news or flash crashes. This strategy will always use a stop loss, but still execution of the SL depends on your broker.
4. Night scalpers are dependent on good brokerage conditions, like low spread and slippage, which might be worse on high lot sizes.

This is a mean reversion strategy around the close of the New York session. It does not use martingale or grid and uses fixed stop losses for every position. 

• Symbols: EURUSD, GBPUSD, EURCHF, USDCHF, USDCAD, EURAUD, EURCAD

Additional information and backtests

Please read the blog post for instructions on how to set up the EA.

Because the EA will trade around the New York close time (16:00 – 18:00 New York time), the GMT time will be different in summer compared to winter (DST: daylight saving time). But the EA has daylight saving times stored internally, so there is no need to adjust the trading hours manually. 

The EA should run on a VPS continuously without interruption (also Friday evening) to store the historic data. 

Please allow web requests to the following URLs for the calendar news filter and automatic GMT offset calculation:

• http://fxdata.cc
• http://backup.fxdata.cc
• http://breaking.fxdata.cc (only needed if you use the breaking news filter)

For backtest it is important to have the correct GMT settings. Ideally, backtests should be done with Tick Data Suite GMT+2 with US DST. 

Because this strategy is trading around swap time the spread can be very large. It is important to use real spread in backtesting and not some fixed spread. But be aware that the spread can be very different between brokers at that time.

The EA should be turned off on days of important events, for example general elections in UK, US or Europe!
