A Saucer With Handle pattern shows a slow decline into the base with sideways trading for several weeks, months or even years. Big cag stocks will be the ones you see typically making saucer patterns, because of their high liquidity (not affecting their price).

A typical saucer correction corrects 12-20% from it’s low (shallower than cup bases);
More volume than up than down weeks;
If it has a handle, it should drift lower for at least a week in light volume.

Buy point
10 cents above the price high on the left of the saucer or 10 cents above the high of the handle;
Like all base breakouts, volume should be 50% higher than average;

Note: The stock may have a lower Relative Strength (RS) because of the length of the base.
