Scalping at the top and bottom of the price range

Description

Back when the selection is trading at the top of its price range or lay when it is at the bottom of that range, and green up later.

This is very similar to trading at support and resistance lines. The triggers watch the money that is being traded at various prices and placed a bet as soon as the last traded price is at the edge of the zone within which the biggest chunk of that money is matched.

The top and bottom of the price range is recognised according to the following criteria: 

Top of the range:

1. The last traded price is equal to the current best lay price.
2. The sum of amounts traded at the current lay price and higher is less than 5% of the amounts traded at current back price or lower.

Here is what the top of the range can look like:

Bottom of the range:

1. The last traded price is equal to the current best back price.
2. The sum of amounts traded at the current back price and lower is less than 5% of the amounts traded at current lay price or higher.

Here is what the bottom of the range can look like:

There must be enough money in the market and on the selection for these calculations to be valid (see constants for the corresponding settings).

You need to have these settings ON for the triggers to work correctly:

Use the following constants to adjust the settings of the triggers:

min_rank Min. rank
max_rank Max. rank
mins_before_start When to start betting, minutes before the off
close_secs When to close all bets, seconds before the off
bet_stop_secs When to stop betting, seconds before the off
bet_size Size of the bet, % of the bank
max_loss Max. loss after which to stop betting, % of the starting bank
target_profit Max. profit after which to stop betting, % of the starting bank
min_price Min. price of selection
max_price Max. price of selection

edge_perc How much the money traded at the edge is less than the rest of selection's matched volume, % of the rest
min_vlm Minimum volume matched in the market
min_sel_vlm Minimum % of market volume on selection

How this works

The tirggers will repeatedly place back and lay bets on different selections in the market, and then close all unmatched/untraded bets at 30 seconds before the off. At the start of an event the market may look like this:
