OK point noted - I have updated record. However my plan was to update that record only once on a weekend but I will do it each time I close out a trade profit or loss. There will some differences in P&L because although my base currency is USD but I'm actually holding the account in USD, Euro & GBP - so currency fluctuation account for differences.
Just to clarify - I'm not really day-trading. That Mexican Peso position was actually entered after market re-opened carried overnight and closed out the next day but in terms of trading session definition it was a day trade.
The reason for quick exit I explained in previous post - the position was strongly correlated to DX position I intend keep for as long as I'm making money - that way using a small account reduces negative account volatility swings associated with long term trading.
To the other poster about credit card - its good business to borrow $10k from credit card and achieve a return higher than card interest. Do the loan amortization calculations.
