Using tick data and timeseries data together

ct

Hi,

I want to use simple strategy. I tried a lot ways but I can't.

Strategy must be use tick data (reading from csv), indicators must be use timeseries (resampled from tick) data

When latest price changed (on tick data):
if latest price (tick) >= indicator (ex: SMA(55)) latest bar close (based on timeseries (ex daily))
buy()
if latest price (tick) <= indicator (ex: SMA(20)) latest bar close (based on timeseries (ex daily))
sell()

Could you help me?

Best,

ct

To simulate a raw tick data one can assign the value of the tick to the fields of the OHLC. See

Community - backtest with tick data, get period datas

With that in mind the value of close (for example) can be used as the tick value (And has to be added with addata)

The 2nd stream, the resampled one, is created, as already present in the code, by issuing resampledata.

The tick data would be in data0 and the resampled in data1
