Specification
I need a developer with very good English skills to provide me the code for a function that I want to insert into my own code and which should do the following:
- Count how many open orders a currency (or an index, etc) is involved in, separately on buy and sell.
- Count the total lot size on buy and the total lot size on sell that the currency (or index) is involved in.
For example, if I have the following trades open:
2 lots of SELL GBPUSD
0.5 lot of SELL EURGBP
0.5 lot of BUY EURUSD
Then the results provided by the function will be:
Total number of open orders BUY on GBP: 1
Total lot size BUY on GBP: 0.5
Total number of open orders SELL on GBP: 1
Total lot size SELL on GBP: 2
Net lot size on GBP (BUY-SELL): -1.5
The function will return the same type of results for EUR, USD and all other currencies, indices, etc that are involved in open orders.
Important: you have to be careful to identify when the currency is the first or the second in the currency pair in order to get the result right. For example, a SELL order on EURGBP counts as a SELL on EUR, but as a BUY on GBP.
The code should also work for symbols composed of only one element, like US30.
Exception: I need an exception to be introduced in the case of instruments XTIUSD and XAUUSD, in the sense that in these cases the function will NOT add these to the count of number of orders and size of lots on USD, BUT it will add them to the count of the number of orders and the size of lots on XTI and XAU respectively.
Use of the function:
I should be able to call this function in the main program something like this: get_lot_count(Symbol), where symbol can be GBPUSD, XTIUSD, US30, etc. When called, the function will calculate and provide (in separate variables) all the information mentioned above in relation to the instrument(s) present in the symbol, regardless of whether there are 2 currencies in the Symbol (like in EURUSD, in which case the information will be, of course, separate for EUR and USD) or a stand-alone instrument in the symbol (like in US30).
I am flexible to suggestions on how to best organise the information.
Note: when applying for this job please let me know if you have experience in doing something similar or other information that would help me understand that you actually looked carefully at the specs and that you are not just sending an “automated” application.
