Single pair trading

In refining my strategy, I'm gleaning through several successful traders' logs. It appears that the most successful traders trade only a single pair.

My current strategy uses (among other things) a modified MACD. I screen about 4 pairs that I use, waiting for an indicator from the MACD (which has proven to be quite predictable). I will switch up pairs week to week.

What are the benefits of staying with a single currency pair? I don't want to buck the trend, if successful traders stay with EURUSD or Cable, I can try that strategy. But a little discussion would be helpful.

Thx.

Its the fact, that once you understand a pair, what makes it move, typically routine, it becomes easier to spot what should happen next, maximising your chances of a return.

But if you take EUR/USD right now, its pretty boring.. basically candle after candle of the same price.

It also depends on your

trading style and strategy. Focusing on one chart may be fine for intraday traders.

I only trade of daily/4hr charts and scan the major currencies looking for price action setups. I Only need a handful number of trades a month to be profitable. Trading one chart would severly minimize my trading opportunities.
