If you are using the static template, then there will be no requests. The data is loaded once from the server.

Like I mentioned in the other issue you posted, try [wallets_exchange_chart] with no arguments. This will load the dynamic template which refreshes via the JSON-API.

(Don’t forget to add a [wallets_exchange_market] or [wallets_exchange_market template="dropdown"] in the same page, so that a market is always selected.)
