EA based on SuperTrends indicator

Below is the Requirements Specification for the development of the Super-Trend Expert Advisor, which is available at https://www.keenbase-trading.com/products/supertrend-indicator/. The link also has code that a developer can use to import the indicator in an expert advisor.

• The idea of the trading system is as follows: market entries are performed when the Sell/Buy Signal appears
• Buy Signal: When price close above the supertrend line.
• Sell Signal: When price close below the supertrend line.
• Positions are closed at opposite signals: Buy positions are closed at Sell signals, and Sell positions are closed at Buy signals. 
• All new positions should have 35 pips stop loss. The EA should allow user to change it. 
• Take profit should be when the opposite signal appears. 
• Positions are opened at the market price when a new bar emerges. 
• Allow user to set number of positions to open 
• When position is 40 pips in profit move stop loss  to break even. The EA should allow user to change it. 
• If the price continues to move in the profit direction, Stop Loss should be trailed by 10 pips.
• Source code for the EA will be required once complete.

Attached is an example of how the indicator works. the link above has more details if you need some.
