A very important point to realize is that once Forex gaps start to fill, this process will rarely stop as there are no immediate supports or resistances to prevent it. Gaps are normally caused in Forex Trading by the speculative small trader who exhibits more irrational exuberance than the large institutional investor. Here is a basic gap trading system developed for the forex market which uses gaps trading to predict retracements to prior price levels.
The trade must always be in the direction of the price. The currency must then gap, perhaps over the weekend, significantly above or below a key resistance level as shown on the 60-minute chart before retracing to its original resistance level. As a result, the gap would then appear to be filled and the price has returned to its prior resistance which has now become its new support. You must then wait until you can clearly identify a candle that signifies the continuation of the price in the original direction of the gap. This action helps ensure that the support has remained intact and presents an excellent entry condition for a new trade with a very good risk to reward ratio.
