Do you really know what these Strategy Properties checkboxes do

Hi everyone,

I'm a Pine script developer and i’ve noticed that many people don’t fully understand what the checkboxes in the **Strategy Properties** section of TradingView actually do. So I’d like to quickly explain them with practical examples:

1. After Order is Filled

Recalculates as soon as an order is opened or closed.
For example, if you have a condition like “move stop-loss to entry after partial TP,” this allows it to update within the same candle. Without it, it only updates at candle close.
Also, if you want to receive **intra-bar alerts**, you must enable this.

2. On Every Tick

As the name suggests, it recalculates on every price movement.
Sounds great, but if your strategy isn’t coded properly, you might see multiple entries for a single signal.
Not recommended in most cases.

3. Using Bar Magnifier

Updates using lower timeframes instead of just the current chart’s timeframe.
Example: when checking past trades, sometimes price touches both TP and SL within the same candle — how do you know which triggered first? With this enabled, the strategy tester knows.
I recommend it, but only if your strategy is coded correctly; otherwise, you might see unrealistic entries before candle close.

4. On Bar Close

Executes trades strictly at candle closes, using the candle’s closing price.
If not enabled, orders are executed at the **open of the next bar** instead.

5. Using Standard OHLC

For charts like Heikin Ashi or Renko (which don’t use real prices), this option ensures more realistic backtests by using actual OHLC values.
If you don’t enable it, your backtest results will be misleading. Definitely use it.

My suggestion:

- Always keep After Order is Filled and Using Standard OHLC enabled.
- If your past trades look clean (no strange early entries), also use Bar Magnifier for more accurate results.

Thanks for reading, stay safe out there!
