Requirement specification (default settings)

This trading system is based on two indicators: renko chart boxes and keltner channel. 
A buy trade is opened if the high value of a renko box is above the upper band value of a keltner channel. 
A sell trade is opened if the low value of a renko box is below the lower band value of a keltner channel.
Either trade is exited when the opposite is true.
If trade 1 and trade 2 is set to true, open two trades at the same time.

Important - this EA has to be able to trade on any instrument on MT4; forex or CFDs for instance.

If it makes the programming easier I can use an EA that takes trades based on when the indicators paint on the chart

Example 1
In this picture you open two sell trades on the first red arrow. 
Since trading every signal is set to false you don't open any new sell signal.

Open two buy trades on the second red arrow and close any open sell order.

Example 2
Trade every red arrow
