I'm using thinkorswim charts for stocks and when i look at the monthly charts the candles each start at the first of the month. is there a charting software that can customize the candles so that a new bar will start on a specified date? say expiration friday for each month. so instead of a candle starting at the 1st of each month it'll start say around the 15th of each month. i spoke to a thinkorswim rep and they say that it couldn't be done with there software. any help will be appreciated, thanks
