I have read dozens of threads saying you need to keep your BTC on a hardware wallet or paper. Anything online isn't safe they say. When trading that is not really feasible is it? I like to move in and out of positions several times a day and often at a moments notice. My trading account has a sizable balance (to me - 5 figures) in it.
How risky is this and any additional things I could do?

You can keep it like that unless and until you are doing the exchange over trusted exchanger site. Storing your coins in the multi wallet like storj and waves is also another good option and is preferred one off course. With Multi wallet you will have options to hold private keys and with that kinda money I believe I will prefer the wallet only. Trades can be done easily as it takes half an hour sometimes more if you have paid low fees for transferring funds from wallet to exchanger. We can tolerate that one without compromising our money.
