special arrow codes

[Forex Trader]

hello, Slawa!

i bring this topic up again, as it is very important to me:
could the special arrow codes be made available for indicators too? the only need is to be able to use the symbols themselves without any special handling, just like the rest of the (non special) codes.

thanks,
adam

psybu please use:
#define C_DN "ê" // -22 for identifying font "Wingdings" character Arrow Down
#define C_UP "é" // -23 for identifying font "Wingdings" character Arrow Up

for arrow down: hold Alt key down, type in 0234, then release Alt key
for arrow up : hold Alt key down, type in 0233, then release Alt key
with quotes " on either side.

hi sx ted,

thank you for the effort! :)
actually the symbols you mention are available as standard arrows, but i also worry about the performance of this solution. (a lot of objects would be created)
