· To: "Metastock" <metastock@xxxxxxxxxxxxx> · Subject: P&F Indicator · From: "Von Hef" <VonHef@xxxxxxxxxx> · Date: Tue, 27 Oct 1998 20:32:16 -0600 · Reply-To: metastock@xxxxxxxxxxxxx · Sender: owner-metastock@xxxxxxxxxxxxx I know its long....but its the best I can do. The following indicator will plot the high of the "x" column and the low of the "o" column in a stairstep manner on a barchart. If the high value changes then the low should hold its value until there is a "P&F" reversal, then as the low changes the high should hold. The first two lines are the Box and Reversal values, and I wasn't sure what the best "Input" values should be so please feel free to suggest any changes. My goal is to design a system around this indicator, to test different Point and Reversal amounts, but its nice to examine the P&F support and resistance levels on a bar chart. Also, I am not as experienced as many on this list nor am I above making errors, so test the value of this indicator for yourself. Here is an update to the P&F Indicator, that corrects a plotting error I found on 1 chart. |
