I need someone to assist me with either option 1 or 2.

Extract from the forum on forexfactory.

(1) First option: You programatically detect in your indicator whether you are running in an online or offline chart. There are various ways to do this. Now when you now that you are in an offline chart, instead of recalculating only the last invalid offset of your indicator buffers (bar 0) you always recalculate all bars. Thus bringing offline file and indicator forcefully in sync with every new tick. The drawback of this option: If you use many bars in your chart or indicator computations are expensive resource-wise, then this will slow down your terminal/charts significantly. Option 1 is the easy option.

(2) Second option: Typically one uses the function IndicatorCounted() or parameter 'prev_calculated' of function OnCalculate() to determine the number of bars to update/recalculate. In offline charts this function doesn't work as expected. It always returns all bars as changed (essentiallly enforcing the solution of option 1). Instead we can emulate the online functionality and if we detect new bars coming in, then we do manually what the terminal would do in an online chart. We shift our indicator buffers with calculated indicator values manually by the number of incoming bars. This shifting can be done in pure MQL but it's slow. I use a DLL function to let C++ do the job for me which is lightning fast. There is one function per buffer type and these functions are part of my MT4Expander which is open-source and available on Github. However, this solution is only suitable for very experienced programmers. In code it looks like in the 3rd screenshot and is part of start() or OnCalculate().
