Trading with one single order or multiple orders?

Hi... I wanted to discuss... about trading with a single order or trading with multiple orders... Advantages and disadvantages of them... Do you trade with a single trade using your leverage? Or Do you trade splitting your leverage in multiple orders ?

I ask this because I know that big trades of banks for example.. they can't put a single trade of 100 million in one trade because the trade would be too big and it reveals information.. so they start to scale in the position in smaller trades until they have the 100 million position.... We small traders don't have this problem of having to hide our positions... all goes to the broker or usually we trade acceptable positions sizes... but what if we use the banks style with small positions? Is there also another advantage of trading with multiple positions? My opinion is it is the worth to investigate at least.

multiple if you have a lot of money on the account!

I prefere cutting up my positions and scalling in/out. This method seems to reduce the drawdowns durring choppy markets as well as produce occasional large gains (when I'm able to get in near a bottom or top.) If the market turns against me, I'm out with a relatively small loss. If the market goes in my favor, I add more partials on failed pullbacks. The newer partials have smaller profit targets and tighter stops as I try to hold the oldest positions as long as possible.

The hard part of this strategy is to hold the oldest position while it's profit diminishes. I'm currently trying to convince myself that the first/oldest position should always be expected to break even so as to insure that I will continue to profit after deep pullbacks. All too often, I let greed win out and I close the position for a small, short-term gain. Soon after, the market trends into to "no man's land" and I'm lost for high probibility signals and quite often I sit and wait while price slowly trends off into the sunset, without me on board.
