MT 4 indicators and EA alteration

Hi, I will provide some indicators which are not functioning as per requirement. They would need additions and alterations. There will also be some new indicators and chart objects to be added. The changes need to be done along with providing the security coding feature which enable the indicators and EA to work as per machine / Login Id and expiry or some unique passwords. Have to also check if the buy sell signals in any of the indicators are having re painting or delay and then it may need to be replaced. The charts features are to have the details dashboard of buy sell entries, re entries, targets, stop loss, trail stop loss and exits . The overbought and oversold alerts are to be added on the charts based on some customization. ( if required).The entire set of indicators and EA will then finally be tested before release of payments. Please offer best as regular work will come.
