1, SAR theory and calculation of
SAR shall cease to move due to a series of end-point indicators constitute a parabolic shape, it will also be known as the parabolic SAR turn indicators.
SAR of the calculation formula is divided into ascending and descending, namely:
Ascending SAR2 = SAR1 + AF (H1-SAR1)
Down-SAR2 = SAR1 + AF (L1-SAR1)
Where: SAR1 ─ ─ yesterday SAR value, the initial value of its type to take up the most recent
Low price, its initial value down-the highest price to take the recent
H1 ─ ─ present the highest price.
L1 ─ ─ the current lowest price.
AF ─ ─ Wilt accelerating factor, the base value of 0.02, when the price of every new high (up-type) or low (down-type), the
Multiplied by 1,2,3 ...... until 0.2 so far, that is, AF = 0.02 ~ 0.2.
Can be seen from the formula, when the initial value of the SAR1 take the recent low, that is, depending on Quotes for the rise, the need to satisfy the current high price of H1> SAR1 conditions. Once the H1 <SAR1, then down-enabled, and Quotes decline, it must meet the current low L1 <SAR1 conditions. The acceleration factor is set, reflecting the market "start �acceleration �slow �zero �reverse starter ... ..." in the process of change, but also resulted in the visual effects the parabola.
2, SAR applications
1, when the SAR price curve down to the bottom buy signal issued when.
2, when the SAR and Vietnam to the top of the price curve when the sell signal.
3, DMI DMI to confirm the market as there is a trend market, SAR indicator buy sell signal issued by the credibility of their technology is high.
