OHLC stands for Open, High, Low, Close.

Zooming in one of these bars, you will notice it looks like –

The mark to the left of the upright bar is the price that the share opened at today. The mark to the right is the price that the share closed at today. The top of the bar is the highest price paid while the bottom of the bar is the lowest price paid. From this you can get a clear picture of what happened to the share overall during trading each day. In the above example, the price opened low, fell a little before climbing strongly.

In the next example, the price rose during the course of the day. However, buying support fell away and the price dropped back to close at the opening price.

The third example shows a trading day where the price fell but buyers saw this lower price as a value buy. This shows support for this stock and the price recovered to close near the open.

The last example shows a stock that opened high and closed low. This is a very bearish outlook for this stock as the sellers were in control.
