英镑高低策略 (GBP Highlow-Strategy)

Hello Traders,

i have a simple strategy for gbp/usd who i trade real a long time. At to many times i was angry that i have no EA for this. So i will post here my strategy and i search help to make an EA. I have no C++ experience.
The idea behind them is to search a trend with new highs and lows. This idea is very old and it give many many strategy with high/lows.

GBP/USD 15min Chart

1. When the 1st 15min Candle closes with momentum above 100 from below we are looking for short trade. If momentum under 100 from below we are looking for long trade.
2. We count 5 bars prior and identify the lowest/highest close of these five bars, this is now our trigger
3. You must wait for a close to have a signal

How to Search the last High/Low
At Nr1. the momentum above 100 from below. Now we have a shorttrigger and wait until a close <trigger
Every momemtum crossing >100 <100 makes a new trigger.
When the momentum >100 we have a new shorttrigger.
When the momentum <100 we have a new longtrigger

I hope my discreption is not to bad with my english
