How to use:

Put your mouse cursor where you need to create a line and push "A" key (if you keep the default key), the line will be created automatically, you can do it as many times as you need.

The lines are drawn with the color and style you choose in parameters.

By default, when the price crosses a line you will receive an alert, or a smartphone notification as you like.

Now you can use a secondary line. So you can use the first line for heavy resistance and support and the second one for alert or small resistance and support. If you want more, I can add more.

• This tools helps you create horizontal lines by just pushing one key on the keyboard, the line will appear at the mouse position.
• You can create as many lines as you want.
• You can choose two colors, one for the support line and the other for the resistance line.
• You can delete easily the last line by a key stroke, you can delete as many lines as you want.
• You can choose to set alarm, when a support or a resistance line is crossed, the indicator will send an alarm on the screen or to your smartphone if you have activated push notifications.
• You can use the same windows to see different chart, the indicator automatically hides support and resistance from other symbol and show it again when you come back to the first symbol.
• The color of the line is automatically chosen, if it's over the market price, it gets a resistance line color, if it's under the market price, it gets a support line color.
• You can see the price of the mouse position in the top left as comment, or you can choose to see it in a floating box.
• On the line, you will see the number of pip separating the line and the actual price. If you put your mouse over it, you will see the price.
• By clicking on the label of the line, you can see the number of times the line was used as Support or Resistance and the number of time it has been crossed; you can choose the number of history. By default it's 200, that means 200 candles in your timeframe, so it can be 200 minutes in M1 or 200 months in MN. You can increase the 200 history if you want. I tried 2000, and it works well. If the candle stops at less than 10 Pips it will appear in the history of support and resistance, but you can change this number in MaxDeviation.
