[Solved] Target rate Notifier

A Currency broker company has asked us to build a system that notifies them when a currency pair rate reaches the target rate. User configures the currency pair and target rate.

The URL to get the Rates in XML form: http://rates.fxcm.com/RatesXML

Example of the rate:

<Rate Symbol=EURUSD>

<Bid>1.38022</Bid>

<Ask>1.38042</Ask>

<High>1.38266</High>

<Low>1.37634</Low>

<Direction>0</Direction>

<Last>10:42:43</Last>

</Rate>

Here Bid is the current rate. Ask is the suggested sell rate. High is day high, Low is day low, Direction is 1=>up, -1=>down, 0=>no change compared to last rate, and Last is the time for last tick.

Design considerations:

–

1. You will need a parser to parse the XML. There are several examples online.

2. Start with hard coded user configuration. For example. Pair: EURUSD, Target rate: 1.381

3. Make it user entry once you have working code.

4. You will periodically check the rates, consider using a schedular.

4. For notification, we will assume that there is a system that will be called to notify users. You only display it on the screen if target has been reached.
