How can we increase the historical data of an indicator if it is ex4 file?

i have an indicator. name is forex indicator pro i think it is a nrp zig zag indicator but when i attach it to mt4 i can only see the 3-4 days historical data is it posible to incrise it . i want to see 4-5 week history .

thanks and best regards

if there is not an obvious setting available for you then you can't, the developer had a reason to set the tool like this.

then is there any other indicator similar to this one that can we see more historical bars
