How to draw support and resistance The most reliable source for identifying support and resistance levels is historical prices, making them invaluable to traders. The key is to familiarise yourself with past patterns – sometimes from very recent activity – so you can recognise them if they appear again.
Simply mark visible highs and lows on your chart; the higher highs and lower highs will serve as resistance levels, whereas the lower lows and higher lows will serve as support levels. It is always recommended that these lines are marked on longer timeframes to have reliable support and resistance levels.
