Creating custom conditional orders using thinkscript

May 16th, 2019, 12:26 PM

Hi guys,

I am trying to create a custom conditional order using thinkscript. The idea is to sell an existing positon if the latest closing price is lower than the lowest price in the previous bar.

The code I currently have is pretty straightforward:
close < low from 1 bar ago

It appears that if I don't define the aggregation period, the system uses daily aggregation per bar. However, I would like to be able use this conditional order in other time frames such as 15 minute, 30 minute...etc., but I'm confused about how to set the aggregation period.

Using 15 minute as the aggregation period as an example, I'm assuming I have to put the code "AggregationPeriod.FIFTEEN_MIN" somewhere, but I keep getting errors in the thinkscript editor.

Any help would be appreciated, thanks.

The default time is whatever your chart is, unless this is a scan, in which case, yes the default is daily. You can customize scans to use timeframes other than daily without writing script for it, but the data is wonky, so I'd caution against it if you need it for reliability. But back to how to use aggregation period, here is an example:

Code

input aggperiod = aggregationPeriod.FIFTEEN_MIN;

def c = close(period = aggperiod);
def l = low(period = aggperiod);
def condition = c < l[1]; 

addOrder(OrderType.Sell_to_close, condition);

One other thing to note on using the aggregation function you must use a chart in a lower time frame than what your calling for (you can't aggregate a 15 minute candle from a daily, for instance, but you can aggregate a daily from many 15s).
