Pivot Expert Advisor Required

Hi,

 Working on the hourly chart I require an expert advisor automated trading script that follows these rules

 SELL TRADE

When EMA 5 closes below the PIVOT

 BUY TRADE

 When EMA 5 closes above the PIVOT

This will be applied to USDCHF, AUDUSD, EUR JPY, EURGBP, USDJPY, GBPUSD, NZDUSD & EURUSD

A secondary rule should apply as follows :

SELL TRADE

Close half the trade IF EMA 5 closes ABOVE S1 but only if it has closed BELOW S1 first during the trade.

If this rule triggers the rule should then become inactive for the current trade 

BUY TRADE

Close half the trade IF EMA 5 closes BELOW R1 but only if it has closed ABOVE R1 first during the trade.

If this rule triggers the rule should then become inactive for the current trade
