Trend Tracker Expert Advisor

1. Basically it's about having a BUY order when the signal is showing buy. As soon as the signal shows SELL, we close the BUY order and open a new SELL, and viceversa.
2. There can be only 1 open order at a time. Opening a new order means closing an existing one.
3. The type of signal (act only upon Swing line, Breakout line, or any) is defined in the list of parameters.
4. The lot size is to be defined in the parameters.

Desired parameters:

• Magic: 8-digit unique Magic Number of the EA (by default "28757148").
• Signal: list. Contains "Swing", "Tracker", "Any". It defines the type of indicator signal to be listening to for opening/closing trades: swing line, tracker line or any of them (by default "Swing").
• Size: lot size of the trades to be opened (by default "0.1").
• Investment: used to calculate dynamic lots based on the account equity (by default "0").
• When zero the lot size will always be fixed as indicated in the "Size" parameter".
• When there is a positive value the lot size will be calculated according to the following formula: Equity / Investment * Size. For instance, if the equity is $1,000, "Investment" is 200, and "Size" is 0.1 the EA will add "0.1" lots for every "200" units of equity, that is: 1,000 / 200 * 0.1 = 0.5 lots.
• Comment: custom comment of the trade (by default "swing").
• Foreground: color picker for the foreground text (by default "White").
