Tick Money Flow, CurrentBid CurrentAsk

[thrunner]

After searching for CurrentBid and Ask and found that it is available in NT, would anyone be interested in tackling this indicator from TS; I apologize in advance if this is the wrong place or way to ask. Thank you :

TickMoneyFlow indicator from TS forum. D=68788&Page=2
The CurrentAsk/CurrentBid function returns the current real-time inside Ask/Bid for the last bar on the chart,
for use in a chart window. 
CurrentAsk/CurrentBid cannot reference historical Ask/Bid data, and returns the Close of the bar for
all historical bars in a chart. Keep in mind that symbols that do not trade directly will report 0;
(e.g. Market Index Symbols).
