+BAIP: 004
+Title: Use 1 hours period EMA(6) to instead of BAIP2

+
+# Abstract
+Use 1 hours period EMA(6) to instead of BAIP2
+
+# Motivation
+BAIP2 track the real-time price too slowly, when the price has plummeted, there will have a big discount space for bitasset, it need two days to repair the price, this will crush the confidence of the holder of bitasset, harm the bitasset.
+
+EMA have a key point is more better than BAIP2: The EMA is a moving average that places a greater weight and significance on the most recent data points.
+
+This FEED PRICE can track the real-time price more quickly, can avoid the lower shadow and repair price more faster(but still need one or two hours to repair).
+
+The one hour will be cooling time.
+
+Shorting attack will need more time to make the price down.
+
+There still have a big discount space, so i think to add the Weighting factor * Current price to make the big discount space more smaller.
+
+Weighting factor * Current price will increase the nondeterminacy of feed price.
+
+# Rational
+
+Follow the BSIP76 and BSIP58.
+
+# Specifications
+
+>**FEED PRICE =max (Weighting factor * 1 hours period EMA(6) + Weighting factor * Current price，Current price)**
+
+Current price : The real-time BTS price of CEX, and notice: we still have many feed provider give a most lower feed price of CEX.
+
+1 hours period EMA(6): Get the latest bar data from CEX，then calculate out the EMA6.
+
+Weighting factor: EMA(6) is the latest bar.
+The Weighting factor of EMA(6)=EMA(6)/(X * current price + EMA(6)), We can try X=6 first，X=(1，10）
+
+## Explanation：
+As the EMA（6）come from the latest finished 1 hour bar, and the current price come from the next hour which the 1 hour bar didn't finish, so the feed price was constituted by a fixed EMA（6）in 1 hour and a variable current price.
+
+If use proportion of weighting factor, the weighting factor of EMA（6）will be great when the price spread became great between EMA（6）and current price, the value of X will determine the upper limit,  if the price spread became small, the weight of EMA(6) will become small followling.
+
+proportion of weight X=3，data come from 1hour EMA6，2020/02/15 22：00 to 2020/02/17 03：00

 ## Explanation：
 As the EMA（6）come from the latest finished 1 hour bar, and the current price come from the next hour which the 1 hour bar didn't finish, so the feed price was constituted by a fixed EMA（6）in 1 hour and a variable current price.

 # Abstract
+
 Use 1 hours period EMA(6) to instead of BAIP2
 
 # Motivation
-BAIP2 track the real-time price too slowly, when the price has plummeted, there will have a big discount space for bitasset, it need two days to repair the price, this will crush the confidence of the holder of bitasset, harm the bitasset.
-
-EMA have a key point is more better than BAIP2: The EMA is a moving average that places a greater weight and significance on the most recent data points.
 
-This FEED PRICE can track the real-time price more quickly, can avoid the lower shadow and repair price more faster(but still need one or two hours to repair).
+BAIP2 tracks the CEX real-time price too slowly, when the CEX price began to move downward, there will appear a big price discount between DEX and CEX, and it needs two days to repair the bts price discount between DEX and CEX, this will crush the confidence of the bitasset and harm the reputation of bitasset very easily，and when the price become continuously falling，then the pirce discount will be very greater，this is very dangerous for the bitassets market.
 
-The one hour will be cooling time.
+# Rational
 
-Shorting attack will need more time to make the price down.
+EMA have a key point is more better than BAIP2: The EMA is a moving average that places a greater weight and significance on the most recent data points.
 
-There still have a big discount space, so i think to add the Weighting factor * Current price to make the big discount space more smaller.
+This new FEED PRICE mechanism can track the CEX real-time price very quickly, and can avoid the lower shadow of price，repair price between DEX and CEX more faster(but still need one or two hours to repair).This repairing price time will be a cooling time for the traders in the bitassets market，and can prevent many unnecessary margin called by the lower shadow of price.   
 
-Weighting factor * Current price will increase the nondeterminacy of feed price.
+The debt Shorting attack will need more time to make the price fall.
 
-# Rational
+To avoid the big price discount between DEX and CEX on price quick falling, so add the **Weighting factor * Current price** to make the big price discount become more smaller，and **Weighting factor * Current price** will increase the nondeterminacy of feed price，this is very important for trading.

 ## Explanation：
 
-As the EMA（6）come from the latest finished 1 hour bar, and the current price come from the next hour which the 1 hour bar didn't finish, so the feed price was constituted by a fixed EMA（6）in 1 hour and a variable current price.

+
+Using proportion of weighting factor, the weighting factor of EMA（6）will become great when the price spread became big between EMA（6）and current price，if the price spread became small between EMA（6）and current price，the weight of EMA(6) will become small followling.
+
+The value of X will determine the upper limit of weighting factor.
