It would be absolutely fantastic if one had some options with how the sharpe ratio is calculated.
since myfxbook calculates the sharpe ratio as the annualized average daily rate of return, which in my opinion suits the intraday trader and discriminates against longer term traders.
an idea on how the sharpe ratio could be displayed on ones myfxbook page, could be as simple as
for daily (D) Sharpe ratio:
for weekly (W) Sharpe ratio:
for monthly (M) Sharpe ratio:
So people viewing myfxbook pages would know at which rate the ratio is being calculated at.
