Traders' Roundtable

now i really feel like a newbie! my intent is to trade one of the donchian systems on TB. i'm not a huge fan of MACD myself but the system says only enter long above zero and short below. lets i want to run a system that uses MACD long avg. (200 days) and MACD short avg. (50 days) but every service ...

how do i get MACD to show up on a third party chart. on TB it just says MACD but when i go to a charting service it is commonly referred to as MACD(12,26,9). TB refers to MACD in only two number terms and all the charting services refer to it in three number terms. please enlighten me.
