MT4 MQL4 Metatrader Indicator

Hi, I need a custom indicator that should work like this: Based on **Two Exponential Moving Average**, In example: 10 and 20period, Indicator should SUBTRACT both indicators value, IE: 10EMA Value = 1.42171 20EMA Value =1.42121 The Result will be 1.42171 - 1.42121 = **50** **I need to be able to SET UP the result amount**. If difference between the two EMA value is 50 (or-50) or more on the live(open) candle, indicator should draw a "check sign" image, and play a sound alarm. If the difference drop to less than 50, then the "check sign" should be removed. AND, when candle CLOSE with the difference of 50 (-50) or more, indicator should draw a "**Thumbup**" on the candle (remove the "check sign" if exist), and plays a different sound alarm. **I need to be able to setup/customize this paramters:** Each EMA Value. **(in this example was 10 and 20 periods)** Each EMA line color. Difference value between them. **(in this example was 50 or -50)** Select the sound file for each alarm or disable them. I want the source code. Job need to be done asap. Maximum budget $100 ## Deliverables ***************** More explanation: See the image attached. Once the open candle reachs a ema difference of XX or more, should play a SOUND1 and show "Check Sign". If that bar closes with the XX difference or more, then should play sound2 and show "Thumbup". Im attaching image to be clear. In the example Im looking for a differemce equal or grater than 8.0pips (80/-80). ******************
