I give it a shot to try to explain why.
Pairs like USDZAR , USDRUB , USDTRY and USDMXN and others moves a lot intraday and many new traders view them as un-affordable and too risky to trade. But it is not, not if you do it the right way.
Look at the left chart showing the USDZAR monthly. Now this an amazing uptrend that started Aug 2011!! and still going strong. It is now very overbought I give you that but in terms of the trend and the strenght of the trend - just look at it! Do I need to predict when this trend is about to reverse in order to trade it at these high prices - No. Do I need to sit and wait for months to enter a trade - No.
So how do I trade it - safely without having to place too wide stops and risk too much per trade.
This is what I do. Now look at the right chart showing the daily. I hope you will see how you easily can trade this pair by just adding and using channels (free indicicator on TV) You can read more about on investopedia if you need to.
I have plotted a few green zones on the chart showing you how the price very often respects the outer boundaries of the LR channel. As well as respecting the inner so called Median price which I have highlighted in red as well. The price doesnt always respect these boundaries - but you only trade when it does.
Now look at the price action and the candles in the zones I have highlighted. It is far from showing them all but enough to give you some good examples on trading opportunities on a pair like this. In these zones I have highlighted you see clear price exhaustion and price reversals. Not always - but often enough for the patient trader.
The key point here is that these are the zones that allows you to enter a trade with a tight stop. When price respect these boundaries it bounces and dont look back for while. Its still volitile movements and big swings but if you enter the trade at the right spot - your stop will be safe and you will be able to lock in a good number of pips by setting your targets just using these LR boundaries as well.
Now compared to a Major pair, which as first glance can move and look just as unpredicatable - depending on time frame . Those pairs offers less in my view since it takes longer time to bag as many pips as one gets on highly volitaile pairs like the example here. And the longer one have to stay or even over-stay in a trade then the more risk you actually take. In highly volitile pairs with large swings one gets so much more when doing it right. I would have to stay in a trade in a major pair for days and weeks etc just to make as much as I make on a pair like the USDZAR in a matter of minutes and hours.
Hope I made some sense here and that these pairs will look less daunting for new traders that reads this posting. If its not your cup of tea then just continue doing what you do.
