@alex81 These are not the buffers used in FX, they are the buffers from the data window, sometimes they match sometimes not, this is why I advised to put the buffer data into a comment block, this shows the data FX can use.
If this code: V_W_A_P=iCustom(NULL,0,"VWAP",0,1); is put into a custom code block then the data window information is put into the V_W_A_P variable the 0,1 relates to the data place in the data window.
