get_fed_watch_target_rate()

Description

Get CME FedWatch federal funds target rate probability forecast data. Returns the target rate range and market-implied probability distribution for each FOMC meeting, sourced from CME federal funds futures pricing.

Return

Parameter	Type	Description
ret	RET_CODE	API call result
data	pd.DataFrame	When ret == RET_OK, returns data
data	str	When ret != RET_OK, returns error description

Data format:

Field	Type	Description
meeting_date	str	FOMC meeting date ("yyyy-MM-dd")
target_range	str	Target rate range, e.g. "4.25% ~ 4.50%"
probability	float	Market expected probability (%), e.g. 92.13 means 92.13%

Example

from futu import *

quote_ctx = OpenQuoteContext(host='127.0.0.1', port=11111)

ret, data = quote_ctx.get_fed_watch_target_rate()
if ret == RET_OK:
    print(data)
else:
    print('error:', data)

quote_ctx.close()

get_fed_watch_target_rate()

Description

Get CME FedWatch federal funds target rate probability forecast data. Returns the target rate range and market-implied probability distribution for each FOMC meeting, sourced from CME federal funds futures pricing.

Return

Parameter	Type	Description
ret	RET_CODE	API call result
data	pd.DataFrame	When ret == RET_OK, returns data
data	str	When ret != RET_OK, returns error description

Data format:

Field	Type	Description
meeting_date	str	FOMC meeting date ("yyyy-MM-dd")
target_range	str	Target rate range, e.g. "4.25% ~ 4.50%"
probability	float	Market expected probability (%), e.g. 92.13 means 92.13%

Example

from futu import *

quote_ctx = OpenQuoteContext(host='127.0.0.1', port=11111)

ret, data = quote_ctx.get_fed_watch_target_rate()
if ret == RET_OK:
    print(data)
else:
    print('error:', data)

quote_ctx.close()

Parameters

// Target rate probability item
message TargetRateItem {
    required string targetRange = 1;     //Target rate range, e.g. "4.25% ~ 4.50%"
    required double probability = 2;     //Market expected probability(%), e.g. 92.13 means 92.13%
}

// Single FOMC meeting forecast
message FedMeetingTab {
    required string meetingDate = 1;               //Meeting date "yyyy-MM-dd"
    repeated TargetRateItem targetRateList = 2;    //Target rate probability distribution (sorted by rate from low to high, probabilities sum to 100%)
}

message C2S {
    optional Qot_Common.QotHeader header = 100; //Quote common parameter header
}

message S2C {
    repeated FedMeetingTab meetingList = 1;      //FOMC meeting forecast list (sorted by meeting date from nearest to farthest)
}

message Request {
    required C2S c2s = 1;
}

message Response {
    required int32 retType = 1 [default = -400]; //RetType, return result
    optional string retMsg = 2;
    optional int32 errCode = 3;
    optional S2C s2c = 4;
