CalcBuySell и getBuySellInfoEx неправильно считают для фьючерсов с валютой шага цены отличной от SUR в форуме Программирование на языке Lua.
Собственно сабж. Брокер БКС, * со срочным рынком, заявки на 2 млн руб ГО могу выставить в торговую систему как на лонг, так и на шорт, однако функции говорят, что не должен мочь:

====code====

maxpos, commis = CalcBuySell(ticker.class, sec, nonfut and "1111111" or "SPBFUTxxxxx", accounts[ticker.class], last, buy, false)
print(maxpos, commis)
debugf(table.tovstring(getBuySellInfoEx("xxxxxxx00000", nonfut and "1111111" or "SPBFUTxxxxx", ticker.class, sec, last)))

Неужели эти функции не умеют до сих пор валютный курс учитывать хотя бы приблизительно?
