trader broker dealer...and some other terms

[yellayella]

I have difficulties understanding the difference between a broker a dealer and a trader.
broker trades on behalf of the trader.
but what is the difference between a dealer and a trader?
moreover there is a low-cost-whatever-the-liquidity trading strategy:
The TRADER places a limit order outside the current bid-ask quotes in order to minimize trading costs. For example a trader may place a LIMIT BUY ORDER at a price below the current market bid. the sstrengt of this strategy is that commissions, spreads, and market impact costs tend to be low….
i dont’t understand this - if somebody (here the trader) wants to buy securites - doesn’t he have to place an order the ask rate.
I think my general confusion is from which perspective to we see this? if i want to buy securites, i look at the ask price - the dealer quotes the bid ( the price at which he buyssecurities) and the ask(price at which he sells securites).
so if i want to place a limit buy order. do i see this from perspective of investor or trader???
thanks.

A broker puts the two counterparties together into a trade i.e. finds each party for the other , usually for a fixed commission .
The dealer waits for the two parties to come to him and collects a bid-ask spread from both together . i.e. he acts as counterparty to both parties. No commission is charged by dealer because he is paid the spread. To get to a dealer too , you might have to pay commission to a broker.

and lets say i want to sell securites - then i look at the bid price. above there was an example from a trader placing a buy order below the bid. but shouldnt he look at the ask??

janakisri said it best.
Trader is the one on the other side of the transaction.
Broker is the intermediary.
