Strategy based on Stoch data from multiple timeframes

Hi traders, I'm trying to backtest my strategy based on checking Stochastic data from multiple timeframes but I have no idea how to achieve this, please help!!

Here is an example scenario:
If Sto %K of '5m' is greater than or equal to 'xx%' AND Sto %K of '15m' is greater than or equal to 'xx%' open a 'Long' order

Hi there

I'd do like this

res5 = "5"
res15 = "15"

f_rsi_stoch(_src, _rsi_length, _stoch_length, _k_length)=>
    _rsi = rsi(_src, _rsi_length)
    _stoch_rsi_k = sma(stoch(_rsi, _rsi, _rsi, _stoch_length), _k_length)
    _return = security(syminfo.tickerid, res, _stoch_rsi_k)

stoch_rsi5 = f_rsi_stoch(close, res5, smoothD, smoothK)
stoch_rsi15 = f_rsi_stoch(close, res15, smoothD, smoothK)

// example with 10%
condition_bull = stoch_rsi5 >= 10 and stoch_rsi15 >= 10

if condition_bull
  strategy.entry(...)
