Are you a daily person? Weekly? Monthly? Quarterly?
Do you have a set amount? Do you chose that amount based on a percentage of your paycheck, or just what you feel comfortable with?
For those that do it very frequently, what is your method of transferring from your bank? It seems very cumbersome to me to have request the transfer, have it go into a core position as cash, and *then* buy the stock/ETF. It's a lot of steps and there is lag in getting the purchase actually done.
