Should i put them before to the MT4 Indicators folder, or it is not nesessary ?

Also I use MT4 platform, i see that many of indicators are from MT5.

So it's not the good way to test the strategy on FSB history data ? Is it better to use MT4 backtester ?

Use MT backtester to confirm that the indicators and signals work well.

I thought that the slippage should make the difference in couple pips maybe, or candles are looking a bit different on each platform.

But for me there shouldn't so much difference to open trades in another way.

I had updated data, and i have no errors in the strategy

I will check the Youtube channel.

If you your strategy has an open position on your backtest (with updated data) and you start the trading, the initial state will be different and the deals will be different.

You have to check for error messages in the MT4 log. You have to consider an eventual slippage and spread change.

Better run the expert on the MT4 backtester for a specific time period and see several entries and exits. Watch also the indicator values.

I recommend you to watch the videos in our YouTube channel. I'm covering many security topics there.

Trades in the FSB, are different than Mt4, i have updated the history today and in the FSB, there should be only buy trades, since 3.04, but on the MT4 strategy opened 2 times short trades after 3.04. I don't have any ambiguous bars in the strategy, no errors.
Maybe you have any idea ?

There is problem also on USDJpy, in FSB on the history it should open couple transactions since start of april, but in MT4, opened just 1 position.
