I am looking to build a web based Equity chart to display performance of FX trading strategies.
I would like to hear opinions and advice on a few areas that I am unsure about.
Equity can - and typically does - change every tick. Should I therefore save equity every tick? If I do I am likely to be saving a lot of data! And then the display of this data will also be a challenge - as there would be a lot of noise.
If I am to save a snapshot every moment in time, what would be a recommend timeframe? Every minute?
Optimizing for download
As the amount of data in the equity chart could be quite large, what are some recommend approaches to optimize for download? Would it be advisable to somehow smooth the equity curve and download just a vector line rather than downloading a csv/json with many thousands of datapoints?
Thanks for any feedback - its really appreciated.
