/*
Theory of operation
-------------------
This is a scalping expert based on cross of RSISlow & RSIFast
This is a STOP/REVERSE system (which means always-in)
(This may need a pip filter for chop)

TIME FRAME
----------
15 MINUTES


SUGGESTED PAIRS
---------------
GBPUSD


ENTRY LONG
----------
RSIFast(Bar[2]) less than RSISlow(Bar[2]) and RSIFast(Bar[1]) greater than RSISlow(Bar[1])

(if RSIType=1, i.e. PRICE_OPEN, then)
RSIFast(Bar[1]) less than RSISlow(Bar[1]) and RSIFast(Bar[0]) greater than RSISlow(Bar[0])


ENTRY SHORT
-----------
RSI4([2]) greater than RSI7(Bar[2]) and RSI4(bar[1]) less than RSI7(Bar[1])


EXIT
----
Sell on cross and take opposite trade


MONEY MANAGEMENT
----------------
-none-


RISK MANAGEMENT
---------------
-none-


FAILURE PROTECTION
------------------
Orders are opened with stoploss and takeprofit of 50 
since it's unlikely to affect scalping, and is safe 
enough in case of power failure or the internet disruption
