The fixed bits at bit positions 1, 3 and 5, and carry, parity, adjust, zero and sign flags are inherited from an even earlier architecture, 8080. The adjust flag used to be called auxiliary carry bit in 8080 and half-carry bit in the Zilog Z80 architecture. Flag chart POPF, POPFD, and POPFQ instructions read from the stack, the first 16, 32, and 64 bits of the flags register, respectively.
POPFD was introduced with the i386 architecture and POPFQ with the x64 architecture. In practical software, the cld and std instructions are used to clear and set the direction flag, respectively. Some instructions in assembly language use the FLAGS register. The conditional jump instructions use certain flags to compute.
For example, jz uses the zero flag, jc uses the carry flag and jo uses the overflow flag. Testing if certain bits in the FLAGS register are changeable allows determining what kind of processor is installed. For example, the alignment flag can only be changed on the 486 and above, so if it can be changed then the CPU is a 486 or higher. Do you look at price charts for your trading?
These are 10 chart patterns that every price action trader should see when they look at a price chart. Reversal Chart Patterns The first five chart patterns are reversal patterns. Typically, they start by trying continue the trend. When that last-ditch attempt fails, the reversal is confirmed. However, remember that most reversal patterns fail, especially when the trend is strong. The bullish pattern has three swing lows. The middle swing low is the lowest.
The line connecting the two swing highs is the neckline. The bearish pattern has three swing highs. The middle swing high is the highest. The line connecting the two swing lows is the neckline. In the bullish instance, the left shoulder and the head highlight the downwards trend. The right shoulder, by ending above the head, halts the bearish trend. The break of the neckline then confirms a change of trend.
Shoulders pattern is a reversal chart pattern. The same logic works for the bearish pattern as well. As it is a reversal chart pattern, we need an existing trend to reverse. A bullish pattern must take place in a downwards trend, and a bearish pattern should take place in a upwards trend. Shoulders formation needed to reverse it. On pullback to the neckline after the break-out.
For the target objective, measure the distance between the neckline and the head. Then, project the distance from the break-out point. A Double Bottom has two swing lows at around the same price level. The swing high in between them projects a resistance line. A Double Top has two swing highs at around the same price level. The swing low in between them projects a support line.
