Re: [amibroker] Puzzelment - RSI of "Foreign" within TimeFrameSet ?

["Tomasz Janeczko" <amibroker@xxxxxx>]

Hello,

When mixing SetForeign with time frame functions you have to
make sure that you call SetForeign BEFORE calling TimeFrameSet.

Also note that RestorePriceArrays / TimeFrameRestore
restores BOTH time frame AND current symbol as explained in the guide:
