taste? statgey taster?

There are two alternatives for renko/range bars.

  1. Use a derivative of the period converter to generate an offline chart. EA must be modified to use the original pair/period not Symbol()/Period() when trading. Not sure you can use the strategy tester at all.
  2. Use a regular chart and convert internally. EA must be modified to calculate ALL indicators internally, but the ST is fine.

Q: How to back test using off-line charts?

A: MetaTrader allows for back testing only on standard time frames like 1-5-15-30-60...
Therefore you need a following trick to do it:
1. go to the c:\Program Files\MetaTrader\history folder. You should see subfolders with
trading servers feeds.
2. make a new subfolder with the name CRB
3. go to one of your trading servers folders ( folder should be in history\xxxx_server) and
copy the following files into history\CRB folder:
- symbols.raw
- symbols.sel
- symgroups.raw
- ticks.raw
- 1 min data, e.g. EURUSD1.hst, GBPUSD1.hst, USDCHF1.hst, etc
4. start MetaTrader and manually log in into account but write CRB in the server field, off
course there will be no connection.
5. restart MetaTrader to clean its preloaded data (you should see Waiting for update on all
charts except 1 min).
6. drop CRB script on 1 min chart but now select a standard TimeFrame to generate, for
example 5 min.
7.

 

I followed this a few days back. Although I couldn't figure out how to do the backtest, at least I can generate the offline chart in Renko look.

I try to do the same today but I can't get the offline chart again. Is it because it's weekend now and there is no live data to tick the live chart and EA and so no offline data/chart could be generated?

Many thanks for your advice!

Figure it out, by giving a manual tick the chart that your renko generator is placed to. You can use this script to make a tick (dll-s must be enabled):

You rock!!! Thanks Erzo!!!!

I can generate a 2-min offline data but can't generate a 5-min one after following step 1-7 above. When I arrive at step 5, I don't see "Waiting for update on all

charts except 1 min". All charts just stay there. Is it because I am in weekend again?

Anyway, I continue to run the 'Tick' given by Erzo but it doesn't help. Still the 5-min 'EURUSD5.hst' remains unmodified. Even if I delete the EURUSD5.hst in the 'CRB' folder, I don't see it being re-created.

Any hint why nothing seems could be created?

Try out a script version of renko generator, it does not need any tick.
