50% is a huge percentage, unfortunately a small amount of money though
It's off of one trade, and my stake was 10%, so a 'bit' on the high side for 'real trading'.
This is the trade....
AUDUSD, weekly support and resistance chart.
You can clearly see it's a significant level.
Then on the daily chart you can see that you can get in close to that level with tight stops.
Sometimes the market doesn't come back close to the level, in which case I'm not bothered, I can't put enough lots on to make a decent profit, better to wait for another. When it does, then great, you need big profits on your winning trades, and using only the levels on your weekly chart keeps you out of more losers.
