MT4 expert Advisor Heikin ashi candles

Project description: Need to build Metatrader EA based on an indicator already built. Having multiple trade conditions to enter a trade and also multiple conditions to exit a trade and close it as required and move stop loss of current trades. Ability to manage time of trade and also manage all errors on the Metatrader to ensure all trades are executed and confirmed. All the parameters should have the ability to be modified based on need. Code need to be error free and more modification may be needed as time passes, all code should be clearly documented and notes written on the code to help future modifications. All transactions should be displayed on the screen of the MT4 or have them viewable at a certain place with the ticket number open.
