Inter-dealer market versus retail tier

Retail sees an access layer, not the whole market

The inter-dealer market is the wholesale layer where major financial institutions trade with each other. Think banks, large liquidity providers, and other professional participants managing real size. The retail tier is different. It is the layer most individual traders access through a broker or trading platform. Your platform may show a clean buy button, sell button, chart, and quote, but that does not mean you are seeing the full institutional order book.

Brokers connect retail traders to prices in different ways. Some stream prices from liquidity providers. Some internalize part of the flow, which means they match or manage client trades inside their own system. Some use a mix. This is why two platforms can show slightly different spreads or fills during fast movement. The market is connected, but retail access is still filtered through infrastructure.

For a $500 account, this is not a reason to panic. It is a reason to test your broker carefully. Watch normal spreads, news spreads, execution quality, stop behavior, and withdrawal process before adding more money. The retail tier can be perfectly usable, but you need to understand that execution is part of the trade. A chart pattern does not protect you from a poor venue, a wide spread, or bad timing during thin liquidity.
